Can drinking lots of water clean out your system from 2 puffs of marijuana in a couple of days?

if you are not a regualr smoker the yes, if you have only taken two hits in the past weeks then you will be fine, the duration of THC in your system varies on the amount smoked, frequency you smoke it, and your individual lifestyle, it stores in fat cells so people with less body fat don't have THC stored in their system for very long at all
