not sure about thc absorbsion rate but i hold for about 10 seconds always sometimes hold for up to 30 if i take a really fat hit. i have also noticed that the longer you hold it the redder your eyes get
D1me Reviewed by D1me on . Holding large hits: Is not a good idea. Wikipedia entry say "A study has shown that holding cannabis smoke in one's lungs for longer periods of time does not conclusively increase THC's effects." and here's the citation they give for that info: "Block RI, Farinpour R & Braverman K. (1992). "Acute effects of marijuana on cognition: relationships to chronic effects and smoking techniques". Pharmacology Biochemistry and Behaviour 43(3): 907 â?? 917." ------------------------ Rating: 5
