Weird advice question

I never used to smoke when I was younger because I was the serious/paranoid/quiet stoner and it just wasn't fun. I recently have experimented with it again and no longer experience above issues...but now I cannot stop falling asleep when I get high!

Is it an issue with the weed quality, or just the way im wired? So odd.

Weed makes you tired the only way to stop it is by smoking more and increasing your tolerance levels of the drug....in time you'll get use to it
