Sorry I speak really candidly about my drug use and some may take it the wrong way, but I will tell you from experience it isn't something I recommend anyone do ever. I have a ton of fucked up stories relating to being under the influence of any number of drugs, but I was lucky and not only lived through my experience but have been clean for a long time now.
Detox was one of the most horrible experiences I have ever been through, the sweats, nightmares, anger and lashing out at people trying to help me, the depression which I still deal with because it triggered a chemical imbalance, the list goes on including my teeth going bad on me years after the fact and sinus problems I couldn't even begin to describe.
So my honest suggestion is not to do them at all. yeah I think weed is ok though I don't touch it very often but thats really about it.
