Stubstance abuser or substance use disorder
 

"Substance Abuse" Is a Label We Should All Reject | Substance.com

I would love to hear your thoughts on this.
For me personally it makes a whole lot of sense.

It does make sense to use language that doesn't classify the whole person but rather his/her addiction itself.

Exactly that's what I like...I feel we can do enough damage to ourselves with our own guilt, shame and self loathing.
The damage of being labelled an abuser by our peers community and society really makes it a tough hole to climb out of.
