Give 3 heath risks for each drug: 1)marijuana 2)opium 3)heroin 4)tobaco 5)cocaine

Marijuana-
Marijuana smoke is filled with many of the same chemicals as tobacco smoke, including ammonia, hydrogen cyanide, and formaldehyde. Some of these chemicals are known to cause cancer. Most users smoke pot in a joint or water pipe, so they breathe the smoke straight into their lungs.

Opium-
Users quickly develop a tolerance and need to use higher, more dangerous doses to get the same high. It can also cause brain damage when taken in higher dosage amounts

Heroin-
Repeated heroin use changes the physical structure and physiology of the brain, creating long-term imbalances in neuronal and hormonal systems that are not easily reversed. Studies have shown some deterioration of the brain’s white matter due to heroin use, which may affect decision-making abilities, the ability to regulate behavior, and responses to stressful situations. Heroin also produces profound degrees of tolerance and physical dependence. Tolerance occurs when more and more of the drug is required to achieve the same effects. With physical dependence, the body adapts to the presence of the drug, and withdrawal symptoms occur if use is reduced abruptly.
