I would definitely recommend that you don’t hang around your friends when they’re smoking…but you will soon realise after a couple of weeks that you function a whole lot better than them. In some ways I look at my smoking friends now and feel sorry for them because they don’t realise what they look like. It only takes one look in their eyes for it to be obvious that they’re not on this planet.

Importantly you’ll see how different people react to them and you.

Occupy your time with some kind of hobby that you love. No doubt someone on here will tell you to "take up sport to show your body what its been missing" or something just as pro-fitness, but the truth is it doesn’t need to be something sporty, just something that can occupy your mind.

The best way to do it is to definitely hide yourself away from your normal social crowd (if they’re regular smokers) for a couple of weeks – don’t go out of your way to do this and be rude, just find other things to do as an excuse. When you do eventually return to them you will immediately see the difference between yourself and them.

Try not to smoke for a minimum of six months socially – not even a toke. After that if you do fancy the occasional toke at a party well then thats up to you – but by then the habit will be broken so you won’t feel the need to smoke every day.

Be confident, feel the difference within yourself and don’t kick yourself if you slip up and have a smoke – just get straight back on the wagon.

Also, drink Orange Juice whenever you can as I’ve found that it counters a marijuana craving (but that could just be me)
