In addition, we have to keep in mind the effects of tobacco smoking on the cardiovascular system, specifically vasoconstriction which decreases cardiovascular tissue perfusion. There is scientific evidence that this has an influence on the rate of nitrogen elimination after the dive. Again, this may increase the risk for a decompression injury. Furthermore, chronic marijuana smoking produces changes similar to tobacco smoking, and therefore it is very likely that it would have the same risks as tobacco smoking. Smoking marijuana immediately prior to diving means diving intoxicated and therefore represents a serious threat to diver safety. It is justified to advise against smoking and diving.
In this article from Dan I found this quote. While it doesn't give a depth limitation as the doctor gave TS, it is rather clear that the risk of DCS is higher in smokers. In this respect it does make sense to keep the nitrogen load lower and dive less deep. Or at least one should think about diving Nitrox on an air schedule.
