In my crash course to new psych techs about addiction I list off all the common legal addictions which goes something like this:

• Caffeine
• Nicotine
• Alcohol
• Gambling
• Pornography
• Social Media
• Binge Eating
• Non-suicidal self-injury
• And depending on the location, Marijuana

I tell them that mine is caffeine and my partner’s is nicotine, then we talk about motivational interviewing and then I move on to dementia.
