You can do whatever you want to do. But, until your son WANTS help, WANTS to get clean- it will not do any good.
I have experience through lives of close friends who have been in and out of treatment for YEARS- wanting to get clean wanting to live sober, and did not stay that way
I don’t want to discourage you to care about your son, but it s a LONG road. A hard road, and YOU can’t fix it. HE can.
You can’t want it for him unfortunately. It takes time, and it can be heartbreaking, but hang in there, be supportive, but don’t enable. Let him suffer his own natural consequences, he will hopefully wake up on his own.

i’m an ex meth addict.

frankly, for this to be successful, he needs to WANT to quit. any amount of pushing or forcing is not going to help matters at all.

going to rehab is all fair and well, but to put it in perspective, if you’re still enjoying the party and don’t want to leave, you’re going to go straight back.

i didn’t stop until i reached rock bottom. and i didn’t go through rehab to quit either. it was just sheer determination to get well after i realised that as a child, i never imagined my life would end up such a disaster.

good luck.
