If you dissect the lyrics of Vintersorg and Otyg, you find countless references to drugs; alcohol primary.
To take a few examples:
In Hednaorden we hear
"Och styrka till sinnet av mjödets sötma" (And strengthened to the mind by the mead's sweetness), and from Hednad I Ulvermånen
"Mot stjärnprakt höjs nu mjödfyllda stop" (Meadfilled stoups are now risen towards the star's glory).
In both Fimbulfolket and Trollslottet, the lyrics tell about
"glömskebrygden" (the brew of oblivion), obviously refering to black-outs caused by alcohol.
The line
"Med törsten av gravölets rus" (With thirst for the grave-beer's inebriation) from I Trollberg Och Skog can only be intepreted as the cravings and withdrawal symptoms of an alcoholic.
In Gygralock, with the line
"Nu hjälpen blott vändelrot och tidebast" (Only valerian root and february daphne can help now), he goes on to other drugs. Valerian root is, as we know, a sedative drug, and daphne is highly poisonous.
And in that vein it goes on. Culminating in Blåkullafärden, where the entire lyrics tell about a big shindig, where alcohol and other drugs doubtlessly flow freely.
