Yea man i'd say go for it.
Coke isn't that bad of a drug at all. It's actually cleaner than speed or ecstacy.

If it's your first time i'd say take half a gram - maybe a small line every 45 mins. The high doesn't last long maybe about 30 mins. If it's base (pure) coke then i'd mix it man maybe with glucose powder.

You can and will want to smoke before, during and after taking it. It's ok to do so, as it won't affect the high that much (for some people it even brings on the high quicker)

You say you probably won't be able to get any for a long time so you won't be able to do it often enough to get 'addicted'.

Also the 'come-down' on coke isn't bad at all the next day.
