I Smoke and I Have Been Invited To Do a Diving Course This Christmas, Is This Dangerous?

I wouldn't say I smoke heavily, probably 10 cigarettes a day for 4 years average, but I have been invited to do a scuba diving course in december and I was wondering whether this could harm me because of pressures and oxygen tanks or anything like that, any help or information is useful to me.

There shouldn't be any issue unless you actually have a lung problem. I'm a pack a day smoker for 30 years and dive both commercially as well as recreationally. About the only issue some smokers have, is a tendency not to be able to equalize as easily as a non smoker. It's due to the irritation smoke causes to nasal passages. No biggie though, you'll still be able to equalize with practise.
Reply:I dunno about Ryan's comment about non smokers having a tank last longer, all else being equal. I usually outlast all the divers I'm with and I'm what would be considered more than a moderate smoker. Report Abuse

Reply:no, but you should try to quit it will help your breathing and make your air last longer.
