Most people see this as a 'harmless' drug, mostly because it has some medicinal properties, and is a naturally occurring substance. Unfortunately this doesn't mean that there are no negative effects on long term users. While this may not be the kind of drug which can kill you with one dose, it can still have devastating consequences for your life over a long period.
Marijuana can cause you to develop mental problems through long term and short term use. Excess use can lead to paranoia, in both the long term and short term. Studies have also shown that prolonged use has a negative impact on mental abilities and IQ. The drug can also lead to apathy and stereotypical 'stoner' behavior, where the user is interested in nothing but the next joint.
Marijuana can also harm a fetus during pregnancy, and lead to psychosis and mental dependence on the drug.
Heroin is commonly seen as one of the most unpleasant drugs available to buy. It invokes strong chemical and mental dependency. The problems caused by heroin are threefold; the actual drug itself which is incredibly harmful to the body; the culture of violence and crime surrounding its sale and production; and associated diseases such as AIDS which are associated with sharing needles.
The effects on the body are extreme - as the drug depresses respiratory function, prolonged use can lead to lung or heart failure! It also has associations with liver disease and pneumonia due the suppression of the immune system.
Secondary illnesses which are associated with heroin abuse include the AIDS epidemic and hepatitis. This is largely due to the sharing of needles, which leads to cross contamination. Both these diseases can be managed, but not cured and greatly affect the lives of those who contract them.
The social aspect, including the dependence upon the drug makes the user incredibly venerable to dealers. Many people are coerced into trades such as prostitution in order to fund their drug abuse.
Cocaine / Crack Cocaine
Cocaine and crack cocaine are similar drugs; crack cocaine is a processed form of cocaine which is mixed with baking soda or ammonia. Drug abuse effects caused by cocaine are severe; often users will continue to take the drug only to avoid the savage withdrawal which the drug causes.
Due to the rise in blood pressure, and resultant rush, there is a high incidence of strokes among cocaine users, as well as a variety of other cardiac problems. The drug is also associated with acts of violence due to the savage rush it entails.
These are just some of the drugs and the effects of drug abuse which are affecting society today. Hopefully you are now a little more aware of the consequences of drug abuse, and can make an informed choice as to whether or not you use.
