If so, this would help to explain your remission because higher relative humidity increases your skin's ability to retain water, and water is the "modulating" factor in "desquamation"; basically what this means is that your skin cells cannot flake or slough off naturally without adequate amounts of water.
As for the "tingling" sensation that you experience, this is, of course, symptomatic of seborrhoeic dermatitis, but its etiology, although probably related in some part to the change in relative humidity, is more likely psychological in origin, which would help explain why marijuana reduces this anxiety-induced inflammatory response in your skin.
If possible, try traveling back to Southern Sweden but continue ingesting marijuana. If your seb derm returns, you will know that it's the relative humidity and not the marijuana which has "cured" your condition. Of course, you could always stop ingesting marijuana for a little while in Oslo and see if the seb derm returns, but that is only if you feel comfortable doing so.
Additionally, it's important that you realize this "tingling" sensation is not necessarily an indication that your seb derm will return. It's probably just anxiety-induced inflammation and many people who do not suffer from seb derm experience it. If you just make an effort to remain calm, it should pass and over time you'll become less susceptible to experiencing it. I would suggest moderate and regular exercise to help reduce anxiety.
