Hello and welcome to Healthcare Magic. Thanks for your query.
can cause gastric irritation and stomach ulcers,which can result in nausea
, loss of appetite and loss of weight. It is unfortunate that your son doesn't seem to realize the harms of smoking and marijuana, despite their recent adverse effects on his health.
In such cases, where the person's motivation seems to be poor, it is better to seek professional help to help him quit. There are psychological therapies which can improve his motivation (motivational enhancement therapy) and also teach him relapse prevention strategies. So, please take him to a psychiatrist
for further treatment.
Wish you all the best.
