I found a matchbox sized vintage fireworks box in the medicine cabinet at home. Inside was 20-30 parachutes.This would most-likely belong to my mother.I'm very upset and shaken since the discovery as of about an hour ago.I need help to identify the substance.Descriptionarachuted - wrapped in small tissue paper balls and tied at the top.The substance is a very light brown-beige colour. It is non-transparent. They are little rocks that look like biscuit crumbs.Background:My father has told me that mum used to like speed 'back in the day'.I'm in Australia so it is unlikely to be crack.Mum is also prescribed dex-amphetamine for ADHD and Narcolepsy so I believe.I can't think of anything else to say, please help. I have taken 3 of the parachutes and have them hidden in my room, so if there's any at-home tests I can do to determine what the substance is or if you need anymore info ask away.Thankyou.
