Overcome Addictions and Obsessions of All Kinds | Dr. Anna Lembke

She defines addiction as continued compulsive use of a substance or behavior despite harm, and says clinicians look for the “4 Cs” (out-of-control use, compulsive use, craving, continued use despite consequences), plus tolerance and withdrawal.

She describes dopamine as a neurotransmitter central to reward and reinforcement, and says the more dopamine released (and the faster it’s released) in the reward pathway, the more reinforcing a substance or behavior becomes; she adds that social media, gambling, and sex activate the same reward pathway as drugs and alcohol.

Using a “pleasure–pain balance” metaphor, she explains that pleasure triggers compensatory neuroadaptations (“gremlins”) that push the system toward pain; with repeated use, the “gremlins” accumulate, shifting the baseline so the person uses mainly to feel normal and experiences withdrawal symptoms (anxiety, irritability, insomnia, depression, craving) when not using.

She says recovery first requires restoring homeostasis—often via abstinence long enough for the brain to rebalance, which she describes as typically 10–14 days of acute withdrawal for most substances/people with many feeling better by weeks 3–4; she also notes medication approaches like buprenorphine or methadone for opioid addiction.

Asked about substituting other rewarding behaviors, she says clinicians “meet patients where they are,” and that even removing one substance (if not replaced or paired with escalation elsewhere) can lead to improvement; she also mentions evidence that quitting alcohol and nicotine together can produce better outcomes than quitting alcohol alone.
