Hold your pot smoke for 3 seconds and exhale, because science bitches. According to Steve Liebke’s 2001 ‘A Cannabis User’s Harm Reduction Handbook,’ “Take small, shallow tokes or pulls. About 95% of THC in cannabis smoke is absorbed in the first few seconds so breath holding is quite pointless. All it really achieves is a far greater amount of tar being deposited in the lungs.”
