I just told a friend that you should never go on the Internet while high. (Yes, I see the irony, and I'm high, so ignore that I thought I had to share that.)
God, I'm rambling two sentences in. Sorry.
As to why you shouldn't go online while high, it's not the obvious lapses in judgement. No. It's the possibility of dropping food that you're munching on in the post-toke high into your keyboard. And it was funnier when I said it to my non-high but moderately-drunk friend. (Well, via text message; he's in NYC and I'm not.)
Yeah. Obviously I need to listen to my own advice.
