Just as the version of hemp sold as - I think - skunk, has a higher concentration of some part of the usual or possible content, the sort grown for paper or long fibres has a far lower level.

Also, grown in places with lower temperatures, the plant still grows quite happily to be several metres tall, but it not likely to produce the highs associated with more tropic climates.

The powers that be seem perfectly willing to allow alcohol to be consumed, and that has far fewer benefits than hemp, and causes distress and injury which seems socially acceptable.

Ecologies and economies could be transformed by having such a useful resource as hemp grown in bulk and freely available.

By the way - when the permafrost really starts to melt, if there's nothing to hold it together there's going to be problems as the land slumps into the sea - and hemp fibre resists waterlogging.
