This is marijuana in its natural state. There are many thin leaves with serrated edges. The whole plant is deep green in colour.

This is a tray containing 4 ounces of usable marijuana. The leaves contain THC which is the active ingredient.

4 bags of marijuana ready for consumption. These are one ounce bags. By Canadian law, having more than ¼ ounce of marijuana on your person makes the crime a felony, not a misdemeanour.

Take a little bit of the usable product and roll it into a cigarette paper. This one contains a filter which is a little bit unusual.

This is a picture of more marijuana with a lump of hash (the brown lump in the middle). A small piece of hash is crumbled into the marijuana tobacco and then the whole thing is rolled into a marijuana cigarette (called a joint, a spliff, and many other names). This makes the high or buzz more immediate and stronger.

A picture of more serious drugs. The pills may be ecstacy, PCP, or one of many other drugs. The liquid and syringes may be used for heroin, morphine, or a whole host of other drugs too. Any of these drugs are extremely dangerous. Much more dangerous than marijuana or hash.

This is your brain. Whole, clean, and full of life.

This is your brain on drugs.
