It takes 3 seconds for 97% of the THC in the weed to absorb into your lungs.... No point holding it in much longer.... unless mentioned above for the lack of oxygen part of the high.

Now i have a question, how long should you keep smoke in your lungs. Till you can't hold it any more? Does it really matter? If this question sounds strange its most likely that my brain is in another place right now. Rating: 5
