How long does weed stay in your system? It depends on numerous factors such as use habits, dosage, physiological factors, etc. So if you have a drug test coming up, here is what you need to know:

Usage Habits

1-time use: your system should be free of THC in 5-8 days

2-4 times per week: you should be clear of THC in 11-18 days

5-6 times per week: you’re looking at 33-48 days. Whoah.

Daily use: 50-77 days…. ok so if you’re chronic, THC can stay in your system for more than two months!

Dosage

While we don’t have the exact figures, presently, the amount of THC your body takes in can definitely affect how long it stays in your blood. The more potent the strain, the more THC metabolites appear. It’s that simple.

Consumption Method

Evidently, it doesn’t matter. Whether you ingest, vaporize or smoke, on its own, consumption method doesn’t have a significant effect. That said, per the point above, if your consumption method allows for more bioavailability of the THC, such as using a bilingual strip to bypass the liver, the THC concentration can be higher.

Physiological Factors

We get it, you work out. Kidding aside, if your body metabolizes faster than your smoking buddy, it’s likely the THC will leave your system sooner. While we can’t tell you how long weed will stay in your system exactly, it’s clear that if you hydrate often, it will help you flush out the THC from your system via urination. Science.

Detoxify

There are many companies touting their detoxification programs. Most would urge you to start multiple days before your test. Two problems, we have yet to come across significant independent studies proving efficacy. Do they work? Problem two, most drug tests are administered randomly, or upon an incident. So, good luck with detoxification. If you have reputable research, please share it with us. There are also risks to detoxifying on your own. Be careful, friend.
