That method will never work, simply because one cannot "sweat out the THC."
Now there are two ways of going about this. If you have a drug test with six or so hours
follow the next steps. I tested this method when I was in high school on myself and
passed multiple drug tests throughout the year. It worked for me and I way about 160 lbs.
and 5’ 9”.
The idea here is to sweat as much of the THC out as you can. The key is to not be lazy
and try not to die of water poisoning. The most important thing here is to stay motivated
to stay out of jail.
First, create a sweat suit using a trash bag with a few long-sleeved shirts and a sweatshirt
with sweatpants. Swallow a B12 vitamin and a niacin pill. Go jogging for 30 minutes
while drinking as much as a gallon of water as you can.
The other way is to sit in a steam sauna for 30 minutes and drink a gallon of water. Jog
for 15 minutes, and you will be clean. Give it at least 12 hours just in case.
