SHOULD "LIGHTS DRUGS" BE LEGAL?

SHOULD "LIGHTS DRUGS" BE LEGAL?
I think that "light drugs" should be legal becouse:
-"light drugs"are the same kind of narcotic like cigarets
(it means that it make the same kind of adicted like them.)
-It is bad when "light drugs" aren`t legal, becouse everybody who wont take that kind of drugs, will be take them. And it doesn`t mather for him how he will buy them.
-When drugs aren`t legal, criminal underworld become to be stronger, becouse th most of their dirty money comes from illegal salling of drugs.
-The situation when "light drugs" aren`t legal is similar like in USA in early years 20th
of XX century when there was a prohibition for alcochol(we all know what that project comes for citizens and for governament. Now it is known that wasn`t good things for honesty people).
