In the Czech Republic, you are allowed to grow own plant with maximum five per personal use. Selling plant with THC is criminal and you will face a huge penalties + jail time. The government figured out that it is not worth to prosecute individual users and old ladies who grow it on its balconies. The biggest problem there are wholesalers who distribute it Germany and Poland. Nonetheless medical pot is allowed, and technical plant without THC is grown all over the country. It has widespread industrial use, you can buy pot pesto, butter, beer, vodka, and even ice cream in downtown of Prague just outside of St. Jill church. Austria has also grows extensively technical plant without THC and you can even stop at some of these farms in Lower Austria. You can even get lost in pot maze

The state police control the plants for industrial use to ensure that THC limit is not reached, and there been issues with industrial growers and the law enforcement for years. Alcohol causes much more damage to the society, so are prescription drugs, and crack. This is real issue which should LE and government to address.
