Historyteach,
Weed, well, you just don't inhale. Bill Clinton.
Actually, it is quite boring for most folks, especially once it makes you more sleepy that it energizes you.
I have noticed that when weed makes you more sleepy instead of more energized, most folks quit...Just like that....
My middle/older brother paid his way through college with duffle bags full of weed.
And the idiot drove a tiny little French car that made police officers stop him just to ask what kind of car it was!
He finally said he had wore out TOO many rear-view mirrors,, so he gave it up.
Now, about once every 8 years, he might partake. But, lucky for him, no withdrawals or regrets.
He is still a wild man, and a millionaire at that,...go figure!
Good luck!
