I would say "Legalize Cannabis" and trough to the garbage the rest of synthetic crap drugs.
he prohibition of drugs through sumptuary legislation or religious law is a common means of attempting to control drug use and the illegal drug trade. Prohibition of drugs has existed at various levels of government or other authority, from the Middle Ages to the present.
Islamic countries mostly prohibit the use of alcohol. Many non-Islamic governments levy a sin tax on alcohol and tobacco products, and restrict alcohol and tobacco from sales or gifts to minors. Other common restrictions include bans on outdoor drinking and indoor smoking. The United States, Finland, Canada, and the USSR also instituted alcohol prohibition in the first half of the 20th century. While most drugs are legal to possess, many countries regulate the manufacture, distribution, marketing and sale of some drugs, for instance through a prescription system.
Many governments do not criminalize the possession of a limited quantity of certain drugs for personal use, while still prohibiting their sale or manufacture, or possession in large quantities. Some laws set a specific volume of a particular drug, above which is considered ipso jure to be evidence of trafficking or sale of the drug.
Drug possession is the crime of having one or more illegal drugs in one’s possession, either for personal use, distribution, sale or otherwise. Illegal drugs fall into different categories and sentences vary depending on the amount, type of drug, circumstances, and jurisdiction.
In the U.S., the penalty for illegal drug possession and sale can vary from a small fine to a prison sentence. In some states, marijuana possession is considered to be a petty offense, with the penalty being comparable to that of a speeding violation. In some municipalities, possessing a small quantity of marijuana in one’s own home is not punishable at all.
