I don't care what drugs people, to each their own, and I agree with allowing people the decision of what they want to do by weighing the pros and cons. With that said, you are comparing weed closely with cocaine. What the fuck? You have to be very misconceived about weed, even comparing it to alcohol, which a lot of people unfortunately do, is a pretty huge leap.
Just to clarify, the only harm weed will do to your body is if you combust it, it can cause smoker's cough and phlegm. It has never been proven to cause even cancer in your lungs. If eaten or vaped, marijuana has no proven harmful side effects (unless you consider increased appetite harmful). Studies show weed consumed daily over decades can even decrease the risk of cancer.
Sorry, just wanted to clarify that since you were trying to compare weed to cocaine, alcohol, and steroids.
Anabolic steroids are synthetic versions of hormones that human body produces naturally. Their main role is to assure increased physical performance in all sports and athletic pursuits. Steroidal compounds enhance stamina, strength, weight and size of muscles and may improve the energy levels during physical training. Oral and injectable steroids posses the ability to increase athletic performance, have a positive effect on red blood cells production and bones density. The steroids are used in accordance with requirement and needs of any athlete individually. There are special compounds which are not suitable for women and a series of anti-estrogen products which main role is to counter the eventual side effects of steroids use and to restore natural testosterone levels of the human body. These compounds nowadays became an important part of muscle building process among professional athletes and bodybuilders, as well as regular people, males and females that have the goal to become more attractive and exhibit good looks.

This is an investigation of whether the real world behaves as predicted by the hypothesis. Scientists (and other people) test hypotheses by conducting experiments . The purpose of an experiment is to determine whether observations of the real world agree with or conflict with the predictions derived from a hypothesis. If they agree, confidence in the hypothesis increases; otherwise, it decreases. Agreement does not assure that the hypothesis is true; future experiments may reveal problems. Karl Popper advised scientists to try to falsify hypotheses, ., to search for and test those experiments that seem most doubtful. Large numbers of successful confirmations are not convincing if they arise from experiments that avoid risk.  Experiments should be designed to minimize possible errors, especially through the use of appropriate scientific controls . For example, tests of medical treatments are commonly run as double-blind tests . Test personnel, who might unwittingly reveal to test subjects which samples are the desired test drugs and which are placebos , are kept ignorant of which are which. Such hints can bias the responses of the test subjects. Furthermore, failure of an experiment does not necessarily mean the hypothesis is false. Experiments always depend on several hypotheses, ., that the test equipment is working properly, and a failure may be a failure of one of the auxiliary hypotheses. (See the Duhem–Quine thesis .) Experiments can be conducted in a college lab, on a kitchen table, at CERN's Large Hadron Collider , at the bottom of an ocean, on Mars (using one of the working rovers ), and so on. Astronomers do experiments, searching for planets around distant stars. Finally, most individual experiments address highly specific topics for reasons of practicality. As a result, evidence about broader topics is usually accumulated gradually.
