Tea has fractions of the mg caffeine that coffee does. It makes sense pharmacologically that you have a higher tolerance than only tea drinkers. I wouldn't recommend using methamphetamine, it is a prescription for ADHD, taking it lightly is not advisable. You can use tea as a tolerance reducer instead, take it on off days instead of coffee.

Methamphetamine is not a prescription for ADHD. Dextroamphetamine, amphetamine, and Methylphenidate are.

They also have controlled release mechanisms and are available in therapeutic doses.

It is not the same thing as buying however much you want of a significantly stronger stimulant and taking and instant hit.

And to anyone not prescribed those medications that are obtaining them for recreational usage, you make an already difficult life of ADHDers much worse, as some are denied an effective, life-changing treatment because of this.

Methamphetamine is sometimes prescribed for ADHD under the name "Desoxyn". While medical professionals appear hesitant to do so, patients who are prescribed Desoxyn rate it much higher than other ADHD drugs.

Yes, I have tried them all. Meth is the best, and most gentle/natural feeling. No question.

It also has the unfortunate side effect of being neurotoxic, which is why only the other amphetamines are used therapeutically.

Neurotoxic at high doses that is. Meth is FDA approved for ADHD and used therapeutically, I take it. It’s certainly the cleanest smoothest gentlest and most effective thing I’ve tried and I’ve tried it all.

Can you name a concrete brand or something to this extend?

Because it's certainly far easier to get in pure form on the black market compared to other amphetamines.

Actually (green) tea leaves have more caffeine per gram than coffee beans do, but in general you use more coffee (~60 g/l) for your cup than tea leaves (~12 g/l) and hotter water, so more caffeine is released.

However, tea leaves are safe for consumption, so you could eat them instead (for example as a salad).

Or for likely the most common form - Matcha, which is green tea leaves ground to a powder.

Matcha is not terribly common in the US. You can find it, but you have to go out of your way to

I drink Yerba Mate tea as a substitute. It contains more caffeine than other teas, plus you can drink it out of a cool gourd. Might be worth giving a try!

Lose doses of methamphetamine are much smoother and cleaner than coffee
