What are the detection methods of heroin, add some images, chemical reactions, pictures etc,. regarding this?

I haven't seen any pictures of people on heroin; however. I have seen people on heroin and didn't know what the hell they where on it was hard for me to figure out. Then I can tell you they act lethargic, clumsy, eyes totally out of the norm they resemble a drunk but there is no smell of alcohol. they can't walk very well. Their bodies are limp and it's scary when it's your niece coming to pick up your great nephew. And believe you me you don't want to mess with me when it comes to protecting a child. I turn in to a mother bear and I have gone to the extremes to stop anyone from driving around intoxicated with a child in the car. I've been cursed and threatened even when I tried to reason with someone on this drug sometimes they listen and just go to sleep and leave the child alone others I have got into physical fights dragging people out of the highways when they turned the car off that I was driving and tried to pull their toddler child out of the car and I didn't know what I was up againist. I went off the deep end and beleive me I protected this child and I got this screwed up person out of the road. This stuff isn'nt nothing to play with and when a person gets on this drug only drug rehab can help, or they will end up dead the fact are they have to be taken off this lightly with the help of a professional drug conselor and a Doctor, or they could die from with drawls. Also they became very slim and there liver can be damaged from the drug, and they usually don't just use this drug it's normally used with other drugs. They need upper to help them have life in them because they can't move very well with this drug and they can become very violent. There a Drug abuse programs that will call you back online. If you are concern about someone please don't help them with money to keep their habit up just try to get a close relative to put them in a in house program. I have a friend whom has a 21 old daugther in jail for the third time because of this drug even though she almost lost the use of her arm and almost died from shooting up with dirty needles. Now we are hoping htat the system will do justice and help her with her drug problem insteed of letting her out to die, or and break more laws and end back in jail again. She use to be a good kid, helped others but it all went in the wrong direction with the involement of one guy and one bad decision, and all her friends and relatives did and does drugs, poor girl hasn't much of a chance, Being shown it was ok and then got into bigger stuff. I hate drugs period. Search on line beleive me if I can find it you can. I'm self taught and I can find things I never dreamed of. I can be nice or a total jerk and I have no tollerance for this around me and if I get pushed to far it can be ugly.
