Statutes of limitations vary from place to place, so it's not possible to give a definitive answer.
Possession of meth in a drug free zone .....
TRANSLATION: "Possession of a Controlled Substance, meaning, Meth-Amphetamine"
A usable quantity for simple possession but there is a threshold amount for other charges such as possession for sale.
Possession with Intent to Distribute?
It depends on what the illegal substance is. Crystal Meth penalties are the highest for possession
15 years -Life in prison.
The charge would be "being found in possession of drugs paraphanalia".
Possession is usually an F5. First offense probably probation. Possibly up to 1 year in prison. Rehab either way.
If there is residue in the pipe and it is a measurable amount then chances are yes they can charge you with possession, meth laws are extremely strict on defendants and even the littlest amount can add up to pretty severe punishment. If there is enough meth in the pipe to cause a positive drug test with a kit, then you're in trouble.
The answer is yes, for a couple of reasons. When the vehicle gets pulled over, the person may toss the drugs on the floor. If he doesn't admit doing that, everyone in the vehicle can be charged with the drugs. If you know that the meth is in the vehicle and you get pulled over and either you or the other people in the vehicle admit that you knew it was there, you can be charged with possession. If the meth user keeps the meth on him and does not implicate anyone else, and no one else admits to knowing about it, then the other passengers should not encounter legal problems.
All of them and then that depends on exactly how much you got caught with and if it is a simple possession charge or a sales or manufacturing charge. If you got caught for simple possession, no they wont. But, if you got caught with 3 grams or better and charged with Sales or Manufacturing, you better believe they will come and get you.
Usually it is a "paraphernalia" arrest - BUT - it might depend on how much residue was in the pipe when it was seized.
