Effects of Marijuana
Marijuana is a combination of shredded leaves, stems and flower buds of the Cannabis sativa plant. Marijuana is the most commonly used illegal drug. Occasional marijuana use is rarely seriously harmful, but smoking pot has important medical effects. Physiological Effects of Marijuana The active ingredient in marijuana is THC. That's short for delta-9-tetrahydrocannabinol. THC is rapidly absorbed after smoking pot. Within minutes, THC and the other substances in marijuana smoke cause short-term medical effects. Signs of using marijuana include:

* Rapid heart rate
* Increased blood pressure
* Increased rate of breathing
* Red eyes
* Dry mouth
* Increased appetite, or "the munchies"
* Slowed reaction time
These effects are reduced after three or four hours. However, marijuana hangs around in your system for as long as a month after smoking. The lingering effects mean you're impaired for several days to weeks after the high wears off. Psychological Effects of Marijuana

According to the National Institute on Drug Abuse, the main effects of marijuana on mood vary and may include euphoria, calmness, anxiety, or paranoia. Getting high or "stoned" is the reason most pot smokers use marijuana. Other short-term psychological effects of pot include:

* Distorted sense of time
* Paranoia
* Magical or "random" thinking
* Short-term memory loss
* Anxiety and depression
These psychological signs of using pot also generally ease after a few hours. But residual effects can last for days. Risks of Marijuana Use
The risks of smoking marijuana go up with heavy use. Although the link has never been proven, many experts believe heavy pot smokers are at increased risk for lung cancer. Heavy marijuana use lowers men's testosterone levels and sperm count and quality. Pot could decrease libido and fertility in some heavy-smoking men. Contrary to what many pot smokers may tell you, marijuana is addictive, at least psychologically. Even among occasional users, one in 12 can feel withdrawal symptoms if they can't get high when they want to. Among heavy pot smokers, the rates of dependence are higher. Many experts also believe that marijuana is physically addictive. Symptoms of withdrawal from pot might include: * Aggression

* Anxiety
* Depressed mood
* Decreased appetite
Marijuana can impair thinking, memory and learning for weeks after use. It produces a range of psychological and physical effects that can be unpredictable at times. It can relieve pain, control nausea and increase appetite. Marijuana typically gives a high, or feeling of well being, which is why it abused. But marijuana can also cause acute psychosis, or a temporary break with reality. Marijuana-induced psychosis happens more often in new users or in people prone to mental illness. Marijuana can cause short-term memory and learning problems, dry mouth, impaired motor skills and red eyes. Within minutes after smoking marijuana, the drug increases the user's heart rate. Heart rates can double in some cases, which is a risk for people with certain heart conditions. Some people may feel relaxed after using marijuana; others may develop anxiety and paranoia. A person's reaction to the drug partly depends on the individual, the strength of the marijuana used and whether the person ate or smoked the drug. Effects of Heroin

Heroin is an opioid - a very powerful painkiller. Heroin mimics endorphins and binds rapidly with endorphin receptors, extending and magnifying their natural painkilling effect. The result is a surge of pleasurable sensation, or "rush." This rush is usually accompanied by a warm feeling and a sense of well-being. Humans are pleasure-seeking entities, and are naturally attracted to things that make them feel good. While it's natural to want to seek out pleasurable...
