Jesuit Priest - I'm still trying to get my head around one of your statements ....
The long term effects of cocaine are still unknown, but it is worthwhile mentioning that no chronic drug treatments' efficacy improves over months.
If the threadstarter can forgive me this little hijack for a brief moment, could you please explain what 'no chronic drug treatments' efficacy improves over months'means ..?
I dont quite understand your wording there.
