Well thc is stored in fat cells, where it can stay for month to a few months like you say, and there's not much you can do about that - my opinion is detox items and the like won't work well, but definitely no harm in trying!
the key things are though: stopping completely asap, staying hydrated and exercising. Burn off the fat = burn off the thc.
Heard someone a while back saying saunas helped, but take that with a pinch of salt.
Basically my advice is your mate just needs to get on a decent health kick. Good diet, high in fibre (to help with digestion), no to little fatty or processed foods (again, fat cells), exercise regularly and hydrate.
Also recommended fasting (skip breakfast, nothing at all one a day week), as without any protein your body will start to use its own fat cells to feed itself.
Important point: Such a drastic change might have negative consequences, so tell them not to push too hard and keep an eye on their general health
hope this helps!
(oh and you can buy piss tests online, might be worth a shout so he can monitor how he is getting on)
