That way you get a larger customer base (for mild ones like cannabis or cocaine, not the hard drugs: its base stays the same) and also keep the price high for them, motivating even more violence for the sales territories.

No, you don't. Not if you actually punish the dealers, something we aren't really doing right now. If you make the risk of selling drugs high enough then it will no longer be considered profitable, and the supply will dry up.

Whenever this is a demand, there is a supply to meet the demand. At all times, under any conditions, not matter what, no exceptions whatsoever.

To even moderately reduce the supply in the face of a demand would require a system more restrictive and lacking in liberty than an Islamic police state.

Sorry, it's not worth the price to keep those who would medicate themselves to death from doing so.
