EDIT: I just realised two things a)We got Indian HAL instead of Indiana Jones and b) a "medicinal" plant from India, grown in the probably remote engine area. Are you thinking what I'm thinking?
Erm... A quick google scan tells me Marijuana is native to the Caucasus... Not india...
In 1785, Jean-Baptiste Lamarck published a description of a second species of Cannabis, which he named Cannabis indica. Lamarck based his description of the newly named species on plant specimens collected in India... The effects of sativa are well known for its cerebral high, hence used daytime as medical cannabis, while indica are well known for its sedative effects and preferred night time as medical cannabis... with some users reporting more of a "stoned" feeling and less of a "high" from C. indica when compared to C. sativa. The Cannabis indica high is often referred to as a "body buzz" and has beneficial properties such as pain relief in addition to being an effective treatment for insomnia and an anxiolytic, as opposed to sativa's more common reports of a "spacey" and mental inebriation, and even, albeit rarely, comprising hallucinations... The terms cannabis or marijuana generally refer to the dried flowers and subtending leaves and stems of the female cannabis plant. This is the most widely consumed form...
Of course, I only meant this as a joke. I mean this is a highly advanced, probably under military governance, ship with a probably omnipresent and all knowing AI on board. So unless the crew was chosen on some very strange standards, or the hippies sent one of their top secret black ops infiltration teams to build a community of peace, love and weed on the new planet, I don't think it's cannabis.
joking: But then again, there are elves (I know they're not DF elves, but stil) on the planet, so one can say that the hippies have been there long before humans... Hmmm... Ancient alien hippy astronauts?
Nowhere else to go except the meshall or further down the hall, so go to the meshall I guess, unless the AI or a forum member has something else/better to suggest.
