0:00:01.083,0:00:03.518 Over the past 20 years 0:00:03.542,0:00:07.375 more than 800,000 people[br]have died in the United States 0:00:07.417,0:00:09.768 due do drug overdose. 0:00:09.792,0:00:12.934 Yes, more than all the lives lost 0:00:12.958,0:00:15.750 in all the wars[br]this country has fought in. 0:00:16.833,0:00:20.417 The majority of these cases[br]are due to opioid drugs. 0:00:21.917,0:00:24.976 Sadly, while we're having[br]this very conversation, 0:00:25.000,0:00:28.476 at least one person will die[br]from a drug overdose, 0:00:28.500,0:00:33.393 and a child will be born[br]experiencing severe withdrawals 0:00:33.417,0:00:36.684 due to in utero opioid exposure. 0:00:36.708,0:00:39.268 Only recently have some[br]pharmaceutical companies 0:00:39.292,0:00:42.601 been held legally responsible[br]for the opioid crisis. 0:00:42.625,0:00:46.184 And compared to their[br]multibillion-dollar revenues, 0:00:46.208,0:00:49.542 the economic penalties[br]they're paying seem minuscule. 0:00:51.292,0:00:53.083 So let me as a question: 0:00:54.208,0:00:57.476 why does addiction[br]and the stigma of addiction 0:00:57.500,0:01:00.042 make it OK to undervalue human lives? 0:01:01.458,0:01:04.726 Ironically, I'm often asked[br]the opposite question. 0:01:04.750,0:01:07.684 Why should we care about "addicts?" 0:01:07.708,0:01:09.684 Sometimes I'm even shouted at 0:01:09.708,0:01:13.559 by people who think that anyone[br]who suffers from a substance use disorder 0:01:13.583,0:01:15.101 brought it on themselves. 0:01:15.125,0:01:16.434 They must be weak, 0:01:16.458,0:01:17.851 they lack any moral compass 0:01:17.875,0:01:19.833 and therefore don't deserve any help. 0:01:20.708,0:01:24.726 But if you know anything[br]about opioid addiction, 0:01:24.750,0:01:28.351 you know that this population[br]does not fit that stereotype -- 0:01:28.375,0:01:30.875 not that any addiction every really does. 0:01:31.875,0:01:35.143 These are mothers, fathers[br]and grandmothers. 0:01:35.167,0:01:37.768 They're teachers, business leaders, 0:01:37.792,0:01:39.059 cheerleaders, athletes, 0:01:39.083,0:01:41.101 nurses and bus drivers. 0:01:41.125,0:01:43.458 They're your brother or sister. 0:01:44.292,0:01:48.333 They represent every fiber[br]in the fabric of our society. 0:01:50.292,0:01:53.809 Yes, each person came to addiction[br]in a different way, 0:01:53.833,0:01:56.726 but a major cause of the current epidemic 0:01:56.750,0:02:00.059 is that medical overprescription[br]of opioid drugs 0:02:00.083,0:02:02.393 for the treatment of chronic pain. 0:02:02.417,0:02:05.559 And that is one thing[br]that makes this epidemic different. 0:02:05.583,0:02:09.708 This particular epidemic[br]was caused by doctors' prescriptions. 0:02:11.333,0:02:15.518 The cycle started when pharmaceutical[br]companies convinced physicians 0:02:15.542,0:02:17.833 that their patients[br]should not feel any pain. 0:02:18.875,0:02:20.393 Opioid makers claimed 0:02:20.417,0:02:23.643 that their very potent drugs[br]would not lead to addiction 0:02:23.667,0:02:26.518 unless individuals[br]were certain kinds of people 0:02:26.542,0:02:28.208 from certain kinds of communities. 0:02:29.083,0:02:30.934 Such disinformation, 0:02:30.958,0:02:33.184 compounded with clinicians'[br]limited education 0:02:33.208,0:02:35.351 and public ignorance about addiction, 0:02:35.375,0:02:37.208 is what created the epidemic. 0:02:38.042,0:02:39.833 So that's how we got here. 0:02:40.875,0:02:42.184 Now the question is: 0:02:42.208,0:02:45.333 how do you treat[br]a national opioid epidemic? 0:02:46.917,0:02:48.226 During an epidemic, 0:02:48.250,0:02:51.476 normally governments, clinicians[br]and scientists are brought together 0:02:51.500,0:02:53.184 to help the afflicted. 0:02:53.208,0:02:56.768 They develop new and even[br]unconventional treatment strategies 0:02:56.792,0:02:59.458 to rapidly address the condition. 0:03:00.167,0:03:03.351 That has not been the case[br]for the opioid epidemic. 0:03:03.375,0:03:05.601 However, the picture is changing. 0:03:05.625,0:03:08.976 We're beginning to see[br]more aggressive government actions. 0:03:09.000,0:03:14.143 For example, the NIH recently started[br]a new initiative called HEAL. 0:03:14.167,0:03:17.059 HEAL stands for Helping[br]End Addiction Long-term, 0:03:17.083,0:03:21.476 and it's designed to accelerate research[br]for pain management and addiction 0:03:21.500,0:03:25.059 through funding new treatment strategies. 0:03:25.083,0:03:28.643 The current treatment strategy[br]for opioid addiction 0:03:28.667,0:03:32.167 is the use of other opioids[br]such as methadone. 0:03:33.292,0:03:38.268 These few medications have been used[br]during the past 50 years. 0:03:38.292,0:03:40.893 They're considered substitution therapy -- 0:03:40.917,0:03:43.500 basically fighting fire with fire. 0:03:44.708,0:03:47.601 They have saved numerous lives, 0:03:47.625,0:03:51.250 yet they're not used[br]by many who still need them. 0:03:52.208,0:03:53.893 Why? 0:03:53.917,0:03:56.434 These medications[br]are themselves addictive, 0:03:56.458,0:04:00.143 and therefore come[br]with many governmental regulations. 0:04:00.167,0:04:04.208 Hundreds of thousands of people[br]must be strictly monitored each day. 0:04:05.000,0:04:06.851 They must find an opioid clinic -- 0:04:06.875,0:04:08.518 often far from home -- 0:04:08.542,0:04:10.917 take their meds and then[br]try to make it into work. 0:04:11.917,0:04:16.750 Obviously, that is not the most effective[br]treatment strategy for an epidemic. 0:04:17.833,0:04:20.542 And it raises obvious questions as well. 0:04:21.708,0:04:24.934 For example: why is the treatment[br]of addiction disorders different 0:04:24.958,0:04:27.101 from other medical disorders? 0:04:27.125,0:04:28.893 With most other medical disorders, 0:04:28.917,0:04:32.500 a nonaddictive, prescribed medication[br]is picked up at the pharmacy. 0:04:33.542,0:04:37.059 Why do physicians treating their patients[br]with a substance use disorder 0:04:37.083,0:04:39.601 have limited treatment options? 0:04:39.625,0:04:40.893 No one ever says 0:04:40.917,0:04:43.393 that two to three treatments[br]are enough for cancer, 0:04:43.417,0:04:45.417 especially when it's not a cure. 0:04:47.875,0:04:51.958 And that brings us[br]to that 200 billion-dollar problem. 0:04:54.500,0:04:58.476 Fighting fire with fire[br]is a reasonable strategy, 0:04:58.500,0:05:01.184 but what about using[br]a different form of fire -- 0:05:01.208,0:05:03.559 a safer form of fire? 0:05:03.583,0:05:07.018 What about actually developing[br]a nonaddictive treatment 0:05:07.042,0:05:08.542 derived from another drug? 0:05:10.125,0:05:11.643 That has been my journey 0:05:11.667,0:05:15.226 towards trying to develop[br]a treatment for opioid addiction, 0:05:15.250,0:05:18.000 and it's taken me in some[br]really surprising directions. 0:05:18.958,0:05:22.226 My journey started with studying cannabis, 0:05:22.250,0:05:25.434 the drug most people call marijuana. 0:05:25.458,0:05:26.851 In order to understand 0:05:26.875,0:05:30.351 how cannabis may connect[br]to combating the opioid epidemic, 0:05:30.375,0:05:35.059 first it helps to understand a little bit[br]about the science behind the drug 0:05:35.083,0:05:36.667 and the politics. 0:05:38.333,0:05:40.309 Cannabis is a complex plant. 0:05:40.333,0:05:43.768 It's actually made up[br]of over 140 cannabinoids. 0:05:43.792,0:05:46.101 Cannabinoids are[br]active chemicals from the plant 0:05:46.125,0:05:49.268 that binds to cannabinoid[br]receptors in our bodies. 0:05:49.292,0:05:53.143 The potent psychoactive cannabinoid[br]that leads to the reward -- the high -- 0:05:53.167,0:05:54.809 is THC, 0:05:54.833,0:05:57.809 which we scientists call[br]tetrahydrocannabinol. 0:05:57.833,0:05:59.125 Pretty simple, right? 0:06:00.083,0:06:03.250 But the politics[br]is a lot more complicated. 0:06:04.333,0:06:05.893 Attitudes towards cannabis 0:06:05.917,0:06:08.893 and the amount of THC[br]that's considered safe to consume 0:06:08.917,0:06:11.726 have dramatically changed over the years. 0:06:11.750,0:06:15.643 In fact, this country's had[br]a roller-coaster relationship 0:06:15.667,0:06:16.976 with the drug. 0:06:17.000,0:06:20.476 Cannabis is either[br]highly demonized or glorified. 0:06:20.500,0:06:22.101 On the demonized side, 0:06:22.125,0:06:25.184 cannabis was deemed[br]a Schedule I drug by the DEA -- 0:06:25.208,0:06:27.143 the Drug Enforcement Agency -- 0:06:27.167,0:06:29.601 meaning that cannabis is considered 0:06:29.625,0:06:32.893 to be a drug of the highest[br]abuse potential 0:06:32.917,0:06:35.208 and to have no medicinal value. 0:06:36.083,0:06:40.518 Moreover, the Schedule I label[br]led to the mass, biased arrest 0:06:40.542,0:06:42.018 for the use of cannabis, 0:06:42.042,0:06:45.059 particularly among[br]young Black and brown men. 0:06:45.083,0:06:46.934 However, things are changing. 0:06:46.958,0:06:49.726 The pendulum is shifting[br]in the opposite direction. 0:06:49.750,0:06:55.684 Today, cannabis is legal for medical[br]or recreational use in most states. 0:06:55.708,0:06:58.893 And a bill is even being considered[br]in Congress to remove cannabis 0:06:58.917,0:07:00.792 from the list of schedule drugs. 0:07:01.708,0:07:05.167 We've also seen a great increase[br]in cannabis research. 0:07:06.125,0:07:09.101 Most research studies,[br]including some of my own, 0:07:09.125,0:07:11.000 focus on THC. 0:07:11.833,0:07:15.768 In fact, our animal research[br]has shown a negative relationship 0:07:15.792,0:07:17.833 between THC and opioid addiction. 0:07:19.083,0:07:20.625 However, as I mentioned, 0:07:21.917,0:07:24.726 the cannabis plant[br]has over 100 cannabinoids. 0:07:24.750,0:07:27.250 So THC was not the only one to study. 0:07:28.083,0:07:30.684 In examining another cannabinoid, 0:07:30.708,0:07:32.018 cannabidiol -- 0:07:32.042,0:07:33.809 that is, CBD -- 0:07:33.833,0:07:36.393 we were actually surprised[br]to see features relevant 0:07:36.417,0:07:40.000 to alleviating opioid[br]addiction-related behaviors. 0:07:40.708,0:07:43.958 So there my journey turned to CBD. 0:07:45.875,0:07:49.434 So what's this CBD that has moved[br]from virtual obscurity 0:07:49.458,0:07:50.726 only a few years ago 0:07:50.750,0:07:52.559 to everywhere in society -- 0:07:52.583,0:07:54.018 in your coffee in the morning, 0:07:54.042,0:07:55.518 your water at lunch 0:07:55.542,0:07:57.125 and your beer at dinner? 0:07:58.625,0:08:01.268 CBD comes from the cannabis plant, 0:08:01.292,0:08:05.518 but in contrast to THC that has the high, 0:08:05.542,0:08:08.875 CBD has no addictive properties. 0:08:09.792,0:08:12.851 We're still trying to figure out[br]how CBD fully works, 0:08:12.875,0:08:15.934 but it is known that CBD[br]alters chemicals in the brain 0:08:15.958,0:08:19.042 that regulate emotions and anxiety. 0:08:20.250,0:08:23.268 Interestingly, giving CBD[br]to our animal models 0:08:23.292,0:08:25.934 that had a history[br]of self-administering heroin, 0:08:25.958,0:08:28.333 reduced their heroin-seeking behavior. 0:08:29.250,0:08:34.559 Specifically, CBD reduced heroin-seeking[br]triggered by environmental cues 0:08:34.583,0:08:36.875 that were previously[br]associated with the drug. 0:08:37.917,0:08:39.393 Let me say that again. 0:08:39.417,0:08:44.309 CBD reduced heroin-seeking[br]triggered by drug cues. 0:08:44.333,0:08:45.851 This is significant, 0:08:45.875,0:08:49.643 because craving is often triggered[br]by the memories of the cues 0:08:49.667,0:08:52.018 previously associated with drug use. 0:08:52.042,0:08:55.851 And craving is a matter[br]of life or death daily 0:08:55.875,0:08:58.684 for people with an opioid use disorder. 0:08:58.708,0:09:00.184 Simply put, 0:09:00.208,0:09:02.309 craving can lead to relapse 0:09:02.333,0:09:04.167 and death from overdose. 0:09:05.125,0:09:08.958 So reducing craving[br]is an important treatment strategy. 0:09:11.125,0:09:13.643 Getting results[br]from animal models like this 0:09:13.667,0:09:17.018 is actually the first critical step[br]in the FDA process 0:09:17.042,0:09:19.250 for developing new medications. 0:09:20.292,0:09:22.184 The next step: 0:09:22.208,0:09:23.500 human studies. 0:09:24.542,0:09:26.101 In our first human study, 0:09:26.125,0:09:28.518 we demonstrated that CBD is safe, 0:09:28.542,0:09:32.500 even though individuals taking it[br]had also consumed a potent opioid. 0:09:33.458,0:09:36.726 Next, to determine efficacy, 0:09:36.750,0:09:38.226 we conducted clinical trials 0:09:38.250,0:09:41.018 and made sure that both[br]the study investigators 0:09:41.042,0:09:42.684 and the study participants 0:09:42.708,0:09:46.708 were blind to the CBD[br]or the placebo substances. 0:09:47.750,0:09:51.559 The results from those studies[br]replicated the findings that we had 0:09:51.583,0:09:53.518 in the animal experiments. 0:09:53.542,0:09:59.434 So now we know that CBD can reduce[br]craving triggered by environmental cues 0:09:59.458,0:10:01.917 in human heroin users. 0:10:02.417,0:10:04.643 What's more, our results demonstrated 0:10:04.667,0:10:09.042 that CBD reduced anxiety[br]associated with the drug use. 0:10:10.542,0:10:14.893 This is also significant because anxiety[br]is another critical factor 0:10:14.917,0:10:16.458 that triggers craving. 0:10:18.208,0:10:22.976 Importantly, CBD also reduced[br]the levels of the stress hormone cortisol 0:10:23.000,0:10:27.458 that is often elevated when addicted[br]individuals are exposed to drug use. 0:10:29.375,0:10:30.684 Another intriguing finding 0:10:30.708,0:10:34.893 was the CBD continued to decrease[br]craving and anxiety 0:10:34.917,0:10:37.500 even a week following its final use. 0:10:38.167,0:10:42.268 This aspect of prolonged efficacy[br]is very beneficial 0:10:42.292,0:10:45.476 for people taking any medication. 0:10:45.500,0:10:48.851 So the evidence is mounting. 0:10:48.875,0:10:53.018 CBD does show potential to reduce[br]critical features for opioid addiction 0:10:53.042,0:10:54.792 such as craving and anxiety. 0:10:56.708,0:11:00.309 But we're still not at the end of the road[br]for medication development. 0:11:00.333,0:11:04.601 The gold standard for medicine[br]established by the FDA 0:11:04.625,0:11:06.583 is large, clinical trials. 0:11:07.708,0:11:11.934 Recently, I was fortunate enough[br]to be given that rare opportunity 0:11:11.958,0:11:14.184 to conduct a large,[br]clinical trial with CBD 0:11:14.208,0:11:16.167 in people with an opioid use disorder. 0:11:17.167,0:11:21.292 And that study is expected to continue[br]for at least another two years. 0:11:21.875,0:11:26.208 CBD is now being investigated[br]for numerous medical conditions. 0:11:26.708,0:11:28.351 Also, during the past decade, 0:11:28.375,0:11:31.518 our society has seen an explosion of CBD. 0:11:31.542,0:11:35.583 It's being put into drink, food,[br]wellness and skincare products. 0:11:36.667,0:11:38.833 They're even giving CBD to pets. 0:11:40.667,0:11:44.375 So is CBD a wonder drug[br]as now touted by many? 0:11:45.292,0:11:47.059 No. 0:11:47.083,0:11:50.143 Does it have potential medicinal benefits? 0:11:50.167,0:11:51.518 It does. 0:11:51.542,0:11:54.143 But the only way[br]to get definitive information 0:11:54.167,0:11:56.726 about CBD's full safety and efficacy 0:11:56.750,0:11:58.792 is through large, clinical trials. 0:12:01.625,0:12:04.976 So is it possible 0:12:05.000,0:12:07.893 that we could actually change the game 0:12:07.917,0:12:10.768 by taking this very familiar plant 0:12:10.792,0:12:15.143 and developing a nonaddictive,[br]FDA-approved medication 0:12:15.167,0:12:17.375 for opioid use disorder? 0:12:19.000,0:12:20.809 Absolutely. 0:12:20.833,0:12:22.893 That is why we're working[br]so hard right now 0:12:22.917,0:12:24.958 to develop a solution based on CBD. 0:12:26.125,0:12:27.417 For me, 0:12:28.833,0:12:32.708 the potential benefits[br]are obvious and also overwhelming. 0:12:33.750,0:12:38.375 It means helping to give families[br]back their mother or father. 0:12:39.333,0:12:43.458 It means having your child[br]graduate from high school or college. 0:12:44.292,0:12:46.101 But most of all, 0:12:46.125,0:12:50.934 it means helping to save many[br]of the hundreds of thousands of lives 0:12:50.958,0:12:53.559 that will otherwise be lost to opioids 0:12:53.583,0:12:55.184 in the next decade. 0:12:55.208,0:12:56.476 Thank you. 0:12:56.500,0:12:59.125 (Applause)
