there is a loss of control over one's actions

Are you speaking of alcohol?
If we rquire protection from the insignificantly small number of drug abusers who lose control, why do we not need protection from the millions of alcohol abusers who do the same?

why do we not need protection from the millions of alcohol abusers who do the same?

We do. The punishments that society inflicts for abuse (not USE, but ABUSE) of alcohol is paltry. I would treat the operation of vehicle with ANY amount of alcohol in system as attempted manslaughter, with permanent revocation of driving privileges the LEAST of the punishments. I would treat any assaults made while under the influence as automatically being aggravated assaults. I would treat public intoxication as of yore: 3 days in the public stocks. Or at least publication of their photo in the paper.
