It isn't true, at least not as a hard and fast rule. Post-legalization changes in demand differ greatly per country. It completely depends on contemporary cultural factors of the country in question.
Your claim is far too open ended to interpret clearly.
A change in demand post-legalization can absolutely be highly variable across different countries/cultures, but unless you can demonstrate a country that legalized cannabis and saw a decline in demand, then your as of yet unsubstantiated claim does not refute mine.
