Can two hits of weed be out of your system in three days?

It is hard to give a definitive answer for this questions, however if you only took two inhales and this was the only time you've smoked there is a good chance it could be out as quickly as a week if you drink plenty of water and sweat a decent amount. However there are no guarantees because gender, weight, activity level, body fat all play a role in the process of THC removal from your body.
