Hi everyone. I have a test soon and the results determine wether my kids can stay living with me so it means the absolute world to me as you can imagine. If I don’t pass I may as well be dead as my girls are my life. Anyhow I’ve been doing some major research into this and I’m talking hours upon hours. From what I can gather the way they get drug metabolites out of hair is to firstly soak in ethanol or methanol and apply heat. They Say don’t use sodium hydroxide with it when testing for certain drugs as it breaks it down too much to test- so if you’re being tested for opiates Cocaine or benzo’s I think adding sodium hydroxide is actually going to stop them being able to get the metabolites out anyway? Sodium hydroxide is basically lye/caustic soda. I’ve been out today and bought some oven cleaner which sodium hydroxide is the main ingredient. Do I dilute this with my shampoo or pout the stuff all over?? It’s actually in shampoo anyway in very small amounts. I’ve also got strong hair bleach and a colour before kit. As I’ve been thinking surely if these hair stripping kits can remove colour from your hair they will remove some metabolites too? Anyway I guess I’m just after abit of advice to see if I’m on the right track and if anyone else has come across some of this information too? I feel like I am on to something just not sure if there’s anything I’m missing? I’d be so grateful for any replies. Thanks
