I'm pretty sure that an after-effect of pot is depression. Go to erowid.org. It lists all the various effects of it, ranging from desirable, neutral, to undesirable. I think I read that depression was an undesirable effect, specifically after the high...obviously.

I know the first few times I got high (actually in the last couple months), I felt super awesome the next day. Now, I don't feel super awesome, but slightly irritated and tired. But that could just be the drag of work and school. Dunno.
misspotn Reviewed by misspotn on . Have you ever had a great trip... but a horrible 'sickness' days later? Hi guys, this is a long read so I'm sorry, but I'd really appreciate if some of you could take the time and check it out and see if you have anything to tell me, because I'm clueless and honestly a little worried about my well-being. I understand if you don't want to, but any insight at all is very much appreciated. So, here goes: Last Friday I had an awesome trip. I was laughing and I was DAMN high. I've never been an avid smoker, only ever having done it maybe 5 times in my life now. Rating: 5
