How Long Do Drugs Actually Stay In Your System?

This is pretty worrying...

Drugs The 'safest' recreational substance revealed

Drug aren’t big, and they aren’t clever.

However, the truth is more people than ever before are using recreational drugs on a semi-regular or regular basis across the country.

We read all sorts of things about how harmful drugs are, but we actually don’t hear much about how long the stuff actually stays in your system after you use it.

That’s all about to change though, after new data came to light which makes for really interesting reading…

As Business Insider reports, traces of most drugs stay in your hair for a whopping 90 days after you use them, but that’s only the half of it.

Worryingly, it’s also been revealed that cannabis stays in your blood for a whole two weeks after use, while alcohol only stays for 12 hours.

Cannabis also stays in urine for 30 days, which is WAY longer than the 5 days it takes for alcohol to leave your system.
