I had a feeling a few weeks ago that my sister was doing meth again and last night I found out that her and her boyfriend almost blew up the garage at my Mom’s house!! The cops told me he was making meth out of a Coke bottle and it exploded when they went out for a cigarette. Thank God no one was hurt. She is 32 years old and she needs to get her act together and grow up! I need to know what’s in meth so I can make sure I get all of her “supplies” out of my Mom’s ASAP. I tried to google how do you make meth no one could tell me what the ingredients are.
