Re: lightheadedness -
Another possibility could be low blood pressure, which could cause strange events. It's happened to me twice as a side effect of meds I was taking. Started to see things as photographic negatives - almost what I would've imagined might be like an acid trip.
Turned out that my blood pressure had dropped very low.
More than likely it's the nicotine factor. try a low nic blend and if it persists, see your doctor, because it may be just coincidental that you feel it's from pipe smoking.
