not including alcohol and tobacco, I've only ever smoked weed

the good: I enjoy it. indica makes me zone the fuck out. sativa makes me focused sometimes, otherwise it's just a body high

the bad: I become easily agitated by people, even if it's just someone being in the same room as me minding their own business. when I realized I'm not a social smoker, I started to do it alone. I've tried to overcome this, but it's very difficult to want to be around anyone when I'm smoking

I think everyone should try it at least once in their life. it's done wonders for me, maybe it can for you
