Had a tenant relapse on crack and stop taking her bipolar meds.

Even if he has been paying on time and keeping up with his bills he will soon relapse so you do not want this tenant.

I try to hire everything done, but occasionally I relapse and fix something myself.

Because of this I kept pissing dirty and going back to jail (Opiates are hell, anyone reading this, if you get surgery deal with the pain because if you ever get hooked, its the worst because the brain compels you to do it even when you know the consequence. it literally pulls you to the drug no matter how hard you try) so I went back to jail a lot of times, 3 months, 6 months, 9 months....I got clean in jail but eventually relapsed and I knew what was coming, more jail....I could not handle it.

They were also smoking inside and were hoarders that relapsed on meth.  1200 sqft of smokey junk left behind which I had the pleasure of storing for 45 days per state law.    

I was 3 weeks labor-abstained but relapsed this morning.  

My only caution is a couple of non-smokers who "quit" I found later had some relapses in the unit.

You could face legal action if he "relapses".

I just swore off tax-related posts, so you are making me relapse @Robert Perkins!

Don drug addicts even with the best intentions if they stay around the same people will fall back into old habits.So even if your son is clean today it's only a matter of time before he gives in again.He has to change his whole environment and even move to another state if need be to get away from dealers and so called friends.Your son will never be cured and it is a life long addiction.All he can do is live day to day and set himself up for success as much as possible to prevent a relapse or the frequency of relapse.Being a parent has to be defined and I am sure currently the drugs take center stage.Even though someone is in their 20's,30's40's physically that does not mean mentally they have the capacity or growth for that age.
