Once you have it all in your lungs, a half second is sufficient. I smoke weed to make my high the most-efficient way possible and it allows me to stay stoned for 48 hours straight, without sleeping.

Remember, it's gonna take a second, or more, to blow it all back out.
beachguy in thongs Reviewed by beachguy in thongs on . People may change how they smoke.. I have read from many members of this site that 90% of THC is absorbed in about 5 seconds after inhaling.. I just saw this on the cannabis.com homepage "Daily Factoid: Donā??t hold your breath. The fat-soluble THC-9 is absorbed by the lungs almost instantly. Exhaling immediately after inhalation expels most of the carcinogenic compounds." So now, this information may change your smoking habits, i know i hold hits in for about 5-10 secs.. but now might cut down on that time! Rating: 5
