Hello Gab, and I agree with James, an interesting post.
The laws in Australia are as confusing as ever, some States have made it legal, while some others are relaxed, so if you smoke it in a legal State then drive across the border, you may be caught, silly conditions and I'm certainly not a weed smoker, however, it's another addiction.
In some jobs, people are drug tested, while not with others, and people use it for recreational purposes and others smoke it all day, but to stop any addiction it needs the person to understand the reasons why they should stop it, and these may change when in use or when they haven't used it, and both of these could be very different.
The doctor can prescribe you with a type of medication that's used for alcoholics to stop them from drinking and the same can happen for people using drugs of any type, so ask your doctor if that's the way you decide.
I often wonder what is the worst addiction, smokes, alcohol, drugs, smoking weed or eating too much chocolate for someone with diabetes, addicts can justify, while those that aren't addicted have another choice and the question remains, why can someone have a drink on weekend at 9 am and not at 6 pm for example.
There are reasons why people become addicts and the list is numerous, but if you are suffering from any type of mental illness, then that's why this could happen.
If you want to stop then that decision has to come to you by yourself but have a chat with your doctor, and please don't be afraid, I'm sure they have discussed this often with other patients.
