Full conversation:

Is cannabis as addictive as other drugs of abuse? It’s been known for decades now that the addictive liability of major addictive substances like alcohol, opiates and stimulants vary depending on the drug itself and how it is administered (injection, inhalation, oral consumption, etc.). In this clip we definitively answer the question how addictive is cannabis? By comparing the cannabis dependency rates to those of cocaine, heroin alcohol and nicotine, along with skyrocketing cannabis potency in terms of THC levels in cannabis increasing from ~3% to ~17% THC concentration on average.

We’re a group of Canadian neuroscientists reviewing the latest news, events and scholarly publications from this week in neuroscience and beyond! In each NeuroDrugs live stream we review classics in the field of addiction neuroscience, as well as newly published articles on a weekly basis.

Part of a longer discussion where we discuss the incentive sensitization theory of addiction. The theory addresses three fundamental questions.
1) why do addicts crave drugs?
2) why does drug craving persist even after long periods of abstinence?
3) Whether ‘wanting’ drugs (drug craving) is attributable to ‘liking’ drugs (to the subjective pleasurable effects of drugs)? Or possibly due to external components altogether.

1. Addictive drugs enhance dopamine transmission in brain reward areas.
2. A major psychological function of this neural system is to attribute ‘incentive salience’ to events associated with activation of the system (drug cues and stimuli).
3. In some individuals the repeated use of addictive drugs produces adaptations in this system, rendering it increasingly and perhaps permanently, hypersensitive (‘sensitized’) to drugs and drug-associated stimuli. This is ultimately a learning & memory based effect.
