marijuana facts...
Usually
smoked as a cigarette or joint, or in a pipe or bong, marijuana has appeared in
"blunts" in recent years. These are cigars that have been emptied of
tobacco and re-filled with marijuana, sometimes in combination with another
drug, such as crack. Some users also mix marijuana into foods or use it to brew
tea.
The
main active chemical in marijuana is THC (delta-9-tetrahydrocannabinol).
Short-term effects of marijuana use include problems with memory and learning;
distorted perception; difficulty in thinking and problem solving; loss of
coordination; and increased heart rate, anxiety, and panic attacks.
