» Drugs Are Not All Equally Bad, Mmmkay?
The Lancet has published a study where scienticians give drugs numeric scores based on various types of harm they cause [login]. The media are liable to give this some attention because they objectively note that there is no correlation between harm and illegality.
You can derive a few interesting ideas from the data that I’m sure the media won’t mention. Such as: despite all the press they get, crystal meth and huffing aren’t really that bad. Perhaps cocaine gets less attention because it has a higher-income following? And I suspect khat might be banned in Canada because only immigrants use it.
The facets of harm they use are Acute Physical (possibility of injury on use), Chronic Physical (injury from long-term use), Intravenous usage (because of side-effects), Psychological Dependence, Physical Dependence, impairment from Intoxication, Social Harm, Health-care Costs, and Pleasure. Although this is a preliminary study and they mention that the facets should be weighted, I believe only the puritan US government would consider Pleasure to be harmful! Therefore, I’ve come up with two weightings of my own:
Selfish
What will give you the most pleasure for the least risk? (Physical harm is weighted twice dependence, because being addicted is less annoying than being dead.)
- Khat
- LSD
- Alkyl nitrites
- Cannabis
- Tobacco
- Solvents
- Alcohol
- GHB
- Ectasy
- Cocaine
- Buprenorphine
- Amphetamine
- Methylphenidate
- Heroin
- Ketamine
- Benzodiazepines
- Barbituates
- Street methadone
- Anabolic steroids
- 4-MTA
(One can’t help but wonder how accurately addiction counsellors can estimate pleasure, although they are precise.)
Altruistic
What has the lowest cost to society? (This is the ranking a non-paternalistic state would base policy on.)
- Khat
- Alkyl nitrites
- Methylphenidate
- 4-MTA
- Ectasy
- Anabolic steroids
- GHB
- LSD
- Tobacco
- Buprenorphine
- Amphetamine
- Cannabis
- Solvents
- Ketamine
- Benzodiazepines
- Street methadone
- Barbituates
- Cocaine
- Alcohol
- Heroin
(Obviously alcohol’s social cost needs to be weighed against it’s cultural value.)
Here’s the raw data so you can play along at home (note that the mean of sums isn’t exactly the same as the means of the authors’ data).



Does it occur to anyone else that the plants we are addicted to are the only ones left with a natural survival advantage?

First of all, I’m pretty upset that I haven’t even heard of half of these drugs (at least the names in this form). Second, my tick list is pathetic.
My understanding of Khat is that you pretty much have to have it fresh, otherwise it’s useless. So given that we probably can’t get the fresh stuff, is the next best choice is either LSD or alkyl nitrites, followed closely by E?
So who’s going to hook us up?

Even without dependence, being liked by humans is a great evolutionary strategy. For example, if only truffles would allow themselves to be farmed, we would cover the earth with them. Another example is that Dawkins thinks that New England trees are being selected for their autumn leaf colour.
“Generally Khat makes an excellent house-plant.” I don’t see much information on popper availability in Canada, but it might be in pharmacies or sex shops – the fastest way would probably be to ask around at Hush.

Looks like a UVic researcher is one of those leading the legalization charge.
