I wonder if tea really is considered a recreational drug given all the health benefits. I personally cannot think of anyone that doesn't at least use caffeine. Even kids do.
You might consider Donald Trump. I don't know if he uses caffeine but he is adamant opposed to tobacco, alcohol and recreational drugs for himself and kids.
Interesting. Neither my husband or I depend on or get anything beneficial from caffeine. He doesn't even like coffee much. Once in a while, on a long drive, he will get a latte/cappuccino to "stay awake". Honestly, I doubt it makes much different other than "it sounds good" and since everyone else says it helps, it's worth a shot.
For myself, depending on what's going on with my body chemistry, coffee/tea can give me a buzz. But to be honest, I don't find it helpful to feel jittery. I'd have trouble sleeping, but it never particularly helped me accomplish my tasks. Most of the time, I don't feel any different after drinking coffee. So I have always been a recreational coffee/tea drinker. I drink it occasionally because I like the taste. Never to "use" it. Maybe 1-2x every 1-2 weeks (mostly because we have a Keurig at work, so why not). If I am in the mood, I drink coffee daily for a week or two before I lose interest again.
Same with alcohol. I don't really understand it when people say it "loosens them up". It makes me giggly and dumb. I don't like the feeling. I do like the taste of froo-froo drinks plus it is a social thing so I try very hard to make sure I don't drink more than 1-2 glasses at a time. I'm a cheap drunk so I have to be careful. I HATE being drunk. A few months back, I was at a girlfriend's house and she kept topping off my wine glass because "it's not good for it to be empty". I watched myself carefully and did not feel any signs and sipped throughout the night. The next morning, I had a my first hangover in many years and I was not happy about it. Took me a couple of hours to start feeling human again. I don't get how on earth that is worth it (I know most ppl handle their alcohol much better than I do). Plus, the calories aren't worth it to me either - I'm weird, but I get just as much enjoyment out of a glass of juice.
If we are expanding the definition of recreational "drug", mine would be sugar. And salt. I'd have a rough time going without.
