I always thought they were free-basing. (It was the early 80's) After all, how would you explain seeing a golden droid levitate before your every Ewok eyes?
some of the finest herb in the galaxy grew on endor's forest moon. during the celebration in the ewok village after the destruction of the death star, lando tried it out by smoking out of a wooden chillum. "i havn't smoked grass that sweet since after the battle of tanaab", he was heard to have remarked. luke, needing to relax after a stressful day, took a huge toke and claimed to have experienced some visuals! he is said to have seen the spirits of obi-wan, yoda, and his old man. god, he was so messed up. the ewoks were amazed when a compartment on R2-D2 opened up and a glass water-pipe emerged held by a robotic grapling hand. the ewoks proceeded to hotbox the **** out of one of their huts. chewie had the munchies so bad that he absent mindedly ate a baby ewok...but everyone was so high that they hardly noticed. princess leia took one hit and passed out, finally giving han the opening he needed. finally wicket...he got so blazed he had no idea what was going on. he played the drums on the stormtrooper helmets late into the night and passed out in a puddle of his own urine.
*ponders that* You forgot to mention the 'shrooms' growing near the outskirts of the Imperial Bunker...
luke had a great deal of experience shrooming ...they used to grow mushrooms on the moisture vaporators of the lars homestead.
chewie had the munchies so bad that he absent mindedly ate a baby ewok...but everyone was so high that they hardly noticed. See it's true! Smoking Ewok herb makes you eat babies!! [Mr Garrison]"Ewok herbs are bad M'kay."[/Mr Garrison]
