If you smoked an ounce, you would more thank likely pass out due to, to much smoke inhalation. I hope you where joking when you said that right? I do not believe you.
Wiz Khalifa, a multi-millionare/rapper can smoke an ounce a day, if he tried.
You on the otherhand probably got to about 1/2 g's maybe 3 if you are lucky.
It's not about what you can handle, it's just a frigg'n spliff!
A bong makes no difference how much thc is extracted, you are lighting all of the bud so you are getting the thc+tar.
A vape is 99% THC and no tar.
For those of you saying that you smoked over an ounce in one sitting is bullshit unless you had more than one person and it was with blunts or j's.
I have smoked an ounce in one sitting with like 5 people and only blunts.
EDIT: On 4/20 there was about 10 people and we smoked almost 3 ounces.
