On occasion I use meth, regular use of pot. I had 4hrs to do hair follicle. So I put lighter fluid on my hair for about 10 minutes, rinsed out. Then put vinegar on for 10mins, rinsed out. Then put lemon juice on for 10 minutes, rinsed it out. Then washed my hair with my regular shampoo and conditioner. Went and took hair follicle, recon what my chances of passing it are
