No, if I can think of a legitimate reason they shouldn't and it doesn't apply to me then why would I be a hypocrite?
When I'm drunk I'm annoyingly affectionate at worst and hilarious at best. When I'm high I just tend to seem pretty normal and smell a bit differently.
There's no down side to me getting drunk or high.
Some people though, are angry drunks. Or they take medications that when mixed with alcohol could kill them.
I know some of my friends are horribly irresponsible whilst high and tend to just make poor decision.
Am I hypocrite for encouraging them not to get drunk or high? Of course not. They are under very different circumstances.
No, because I don't do either. Before you accuse me of being self-righteous, I want you to know that I think it's fine if you do (as long as you are being responsible about it), it's just my choice that I don't.
