Lol because there's no side effects / risks / addiction potential in sedatives/hypnotics?
Mm, yes.
I use weed and Ambien for sleep (not both all the time, but you get it) and while I Ambien suits me very well, I can see the abuse potential and know a lot of people who choose to avoid it due to all manner of behaviour. And very often nowadays, what is prescribes for slight insomnia is something like a small dose of seroquel, which is practically poison compared to weed. Originally it was meant only for the most severe manic schizophrenics and bipolar patients. Then they started pushing it "a little" and despite being fined for hundreds of millions for bad marketing practices, it's still pushed a lot.
"Take a sleeping pill"
Why not cannabis? Smoking is unhealthy, yes, but herb vaporisers are pretty innocuous as delivery mechanisms.
