Smokeleaf leaves prepared in small rolls for smoking. The drug improves mood, but also increases appetite, reduces focus and slows movement. Smokeleaf use can produce a dependency. Can be produced without equipment, at a crafting spot.
Since Smokeleaf can be crafted in early game, in mass without any research need (like the other drugs), and its relatively low addiction rate, it is good for either sale or domestic use.
The default drug policy allows colonists to smoke a toke whenever they feel like it. This can burden a colony with reduced productivity, so it may be worth changing the default policy immediately upon starting a new colony.
In the current game version, taking one smokeleaf joint every two days will not cause dependency. Pawns with the chemical interest or related traits will however override regulations to smoke, giving it an addiction risk. In addition to the stat changes, colonists gain a mellow +15 mood buff while stoned.
High from 1 joint with no tolerance lasts 12 hours.
The game actually recognizes the character binge as alcoholic mental break (major drug binge).
