Or just “I don’t do drugs”, or “I don’t do recreational drugs”?
Or “I don’t smoke weed” and “I don’t drink alcohol” when they come up, separately?
I wouldn’t generally say it at all unless I’m in a situation where I’m offered recreational drugs such as cannabis or alcohol.
My understanding is the term ‘straight edge’ might be more well known than ‘teetotal’, but neither are completely known by everyone.
I take straight edge to mean not doing any recreational drugs. However I read that straight edge can have punk culture connotations that some people might maintain are part of it. Like I might meet a punk straight edger who claims I’m not really straight edge unless I have connections to the punk scene. They also apparently often claim you need to be vegan to be straight edge, I am vegan though coincidentally but not for reasons relating to straight edge culture.
Teetotal I believe most often means abstinence from simply alcohol, but can be used to mean abstaining from all recreational drugs (I think). It may be more well known as just not drinking alcohol. For example teetotallers often still smoke weed.
Apologies if I misrepresented any of these terms.
I used to do a lot of drugs in my 20’s (not so much anymore) and never once did I see someone actually try to convince someone to do something they didn’t want to do.
Like others have said, you’re in the wrong crowd if people are making a huge deal out of this. I wouldn’t trip out on labels.
