But for a while now, it's been produced in a different way. And a big thing is that it's cut with less crap. An analysis of meth samples in the US done by the Drug Enforcement Administration found that in the late 90s, the purity of meth that you'd buy on the street was about 20%. Fast forward more than 20 years. On average, it's almost 97% pure. That is Walter White-level pure.

So now let's find out what meth, just meth, is doing to our brain. And I really wanted to understand just what it felt like to take meth. So I reached out to our listeners who had tried it and had these awesome conversations about the highs and the lows of using meth. So here's how they described what meth can feel like.

So how can meth make you feel this way? Turn on the happy in your head. I talked about this with Professor Martin Paulus, scientific director at the Laureate Institute for Brain Research. And he loves studying meth. He loves watching TV shows about meth.

So Mun told me that meth releases a bunch of chemicals into our brain, like adrenaline and serotonin. But a biggie is dopamine, which is kind of like the feel-good chemical. And meth does this pretty cool stuff to get dopamine really working in your brain.

Normally what happens when you do nice things that bump up your dopamine, not meth, but let's say you have a little sex, you eat a little chocolate, you get a little dopamine hit.

What methamphetamine does... Is it floods parts of your brain with dopamine, but then... It stops that sucking up. And the fact that then it stops it getting sucked back, so the dopamine will hang around for longer as well?

Studies in rats have found that meth increases dopamine in a part of their brain by more than 1,000%. Compare that to cocaine, which bumped up dopamine by a measly 350%. Meth also crosses the blood-brain barrier really quickly, so if you're snorting, injecting or smoking it, it means you can get high super fast. Plus, that high can last for hours, some eight times longer than coke.
