A bicameral legislature, one house elected by mixed member proportional system and the other selected at random from the voting age population. Legislation must pass both houses, if it passed one house but not the other it can go to referendum at the same time as the next general election.
You can also have things like citizen initiated referenda. Campaign finance laws similar to those in the UK are also desirable.
100% agree!
As an addition to this I firmly believe medical marijuana is a phase.
Now I've made people angry here's the nuance.
CBD/THC combinations certainly have a role in some patients with chronic pain, especially where it's use can avoid or reduce the use of opioids.
There are clear specific uses such as intractable epilepsy where it is clearly the best treatment. It is effective for glaucoma but there are better treatments available.
I'm highly suspicious of marijuana having any role in mental health and there are, in my opinion, no convincing studies published showing that it is useful at all despite the fact that large studies have been done and presumably file-drawed.
The idea that smoking is an appropriate delivery method for a medication when other methods are available is insane. Very few things are as bad as tobacco smoke but inhaling smoke is bad for you.
My prediction is that in 20 years we will have cannabis derivatives in capsules that fulfil the specific purposes and the idea that any doctor prescribed marijuana to smoke will seem insane to younger doctors.
