In my college once i was coaxed by my friends to have a few puffs of the pot , i also did part because of curiosity , part because it made me feel that i am doing something a man shoul do (all bull-sh!ts for me now) , i felt good but later i felt dizzy , and lost my concious , i woke up next day after about 19 hrs of sleep , that was my first time and my last also , so i am asking you 2 things : 1. Have you ever done Marijuana during your life ? 2. If yes and you are still doing (or you know who is doing)then please read the next few paragraphs ..... Effects on the Brain: Scientists have learned a great deal about how THC acts in the brain to produce its many effects. When someone smokes marijuana, THC rapidly passes from the lungs into the bloodstream, which carries the chemical to organs throughout the body, including the brain. In the brain, THC connects to specific sites called cannabinoid receptors on nerve cells and influences the activity of those cells. Some brain areas have many cannabinoid receptors; others have few or none. Many cannabinoid receptors are found in the parts of the brain that influence pleasure, memory, thought, concentration, sensory and time perception, and coordinated movement. The short-term effects of marijuana can include problems with memory and learning; distorted perception; difficulty in thinking and problem solving; loss of coordination; and increased heart rate. Research findings for long-term marijuana abuse indicate some changes in the brain similar to those seen after long-term abuse of other major drugs. For example, cannabinoid (THC or synthetic forms of THC) withdrawal in chronically exposed animals leads to an increase in the activation of the stress-response system5 and changes in the activity of nerve cells containing dopamine6. Dopamine neurons are involved in the regulation of motivation and reward, and are directly or indirectly affected by all drugs of abuse. Effects on the Heart: One study has indicated that an abuser's risk of heart attack more than quadruples in the first hour after smoking marijuana7. The researchers suggest that such an effect might occur from marijuana's effects on blood pressure and heart rate and reduced oxygen-carrying capacity of blood. Effects on the Lungs: A study of 450 individuals found that people who smoke marijuana frequently but do not smoke tobacco have more health problems and miss more days of work than nonsmokers8. Many of the extra sick days among the marijuana smokers in the study were for respiratory illnesses. Even infrequent abuse can cause burning and stinging of the mouth and throat, often accompanied by a heavy cough. Someone who smokes marijuana regularly may have many of the same respiratory problems that tobacco smokers do, such as daily cough and phlegm production, more frequent acute chest illness, a heightened risk of lung infections, and a greater tendency to obstructed airways9. Smoking marijuana possibly increases the likelihood of developing cancer of the head or neck. A study comparing 173 cancer patients and 176 healthy individuals produced evidence that marijuana smoking doubled or tripled the risk of these cancers10. Marijuana abuse also has the potential to promote cancer of the lungs and other parts of the respiratory tract because it contains irritants and carcinogens9,11. In fact, marijuana smoke contains 50 to 70 percent more carcinogenic hydrocarbons than does tobacco smoke12. It also induces high levels of an enzyme that converts certain hydrocarbons into their carcinogenic form—levels that may accelerate the changes that ultimately produce malignant cells13. Marijuana users usually inhale more deeply and hold their breath longer than tobacco smokers do, which increases the lungs' exposure to carcinogenic smoke. These facts suggest that, puff for puff, smoking marijuana may be more harmful to the lungs than smoking tobacco. Other Health Effects: Some of marijuana's adverse health effects may occur because THC impairs the immune system's ability to fight disease. In laboratory experiments that exposed animal and human cells to THC or other marijuana ingredients, the normal disease-preventing reactions of many of the key types of immune cells were inhibited14. In other studies, mice exposed to THC or related substances were more likely than unexposed mice to develop bacterial infections and tumors. I learned my leasons , hopefully others also do the same before its too late.

When I met my husband he was smoking pot, as were all of his friends (still do). It took awhile but I finally succumbed to trying it. We were in the car at the time and I found driving on the road in the dark a little dizzying. I smoked it for awhile and then I had some once that my soon-to-be husband negelected to tell me was a little more potent than usual. I had a wicked trip. Spent the evening driving the porcelain bus as my s/o looked on with amusement. I will never touch the stuff again. It had made me dizzy on other occasions and really, it tastes like crap and stinks. I have a chronic pain illness and have had several people try to convince me that pot would help with my pain. I don't believe it (my husband needs medication when he hurts his back) and I can't stand the side effects. Besides, I know the harm it can do to the brain cells and have seen the effects on my husband. It's just not worth it.
