Firstly I have to explain what is meant by the definition “soft drug”. Mainly the term regards drugs which are not psychoactive and are non-addictive (or the risk of addiction is minimal). Commonly cannabis has been called soft drug. However in the United Kingdom Misuse of Drug Act 1971 amphetamine, codeine and methylphenidate comes under the same class B drugs as cannabis which makes them equally risky.
While some scientific researches show that frequent use of cannabis irreversibly damages brain and amphetamine destroy liver and nervous system, other researches proof that legal stimulants such as tobacco and alcohol are much more perilous than illicit drugs. Apart from scientific research many countries employ no tolerance policy for any drugs. Concern about health of citizens is the main reason for that. It must be said that all stimulants are highly addictive and legalizing more of them, which means easier access, might effect in rise up in number of drug dependence cases.
However there is a high demand for drugs amongst teenagers, students and employers at all levels. Current pace of life favours use of stimulants either for focusing during long, working hours or relaxing in free time. The market is still growing and looks like a bucket without bottom. If governments would legalize soft drugs with taxes on it, profit from sales could go into their budgets instead of feeding pockets of cartels and gangs. It
