2001 IDMU Drug User Survey
First results from the 2001 IDMU Regular Users Survey show a continuing fall in British cannabis prices, and evidence that cannabis users are smoking more as a result.
Cannabis Market Shares - Domestically-produced cannabis now accounts nearly half the UK market, largely displacing imported herbal cannabis, and Moroccan resin (commonly known as soap-bar), which dominated the UK market during the 1990s, has been overtaken as the market leader by home-produced Skunk.
By 2001 domestically-produced cannabis accounted for nearly half of UK consumption, the market share of skunk now exceeding that of Moroccan (soap-bar) resin for the first time. Skunk was not specifically mentioned in 1984, although Home Grown then took up around 10% of the UK market, and leaf material still adds roughly 1/4 to the recent figures for skunk consumption. In 1984 Lebanese was the most common form of cannabis resin, although this has been rarely seen in the UK since the late 1980s, to the extent that it was removed from the surveys from 2000 on, although press reports suggest production in the Beka a valley to have resumed recently..
It is interesting to note that average monthly cannabis use rose sharply in 2001, accelerating the trend since the mid 1990s, which may reflect price elasticity, as respondents are still spending similar amounts, but are now able to buy more cannabis for their money. Note: The 2002 results should show whether the high level of use in the 2001 survey was a statistical blip (due to the smaller sample and narrower regional user base) or a continuation of the upward trend.
Cannabis prices rose sharply in 1985-86 and peaked in the late 1980s, but have been falling steadily since the early 1990s, and more substantially since 1998. The past four years have shown a steady shift of the deal price from £15 down to £10, such that by 2001 £10 was overwhelmingly the most common price.
Other than competition between resin and the higher-quality skunk cannabis, there would appear to be no clear reason why cannabis prices have fallen so sharply, for instance there is no evidence of reduced demand for the drug " indeed consumption has been rising since 1998, It is possible that cannabis importers and distributors have become more professional and efficient in their trafficking methods.
Although prices for amphetamine have remained relatively stable, average purities increased four fold between 1994 and 1998/9. From 1998 onwards, respondents were asked to distinguish between low quality (street) and higher quality (base) amphetamine, partly responsible for the apparent fall in (particularly) ounce prices, and subjective ratings of the drug.
Cocaine prices have remained broadly stable, an ounce (28g) would typically sell for around £600 (range £500-£1600), with £50 overwhelmingly the most common gram price, although by 2001 the price trend again appears downwards.
Heroin prices have fallen, and the size of bags has increased, to the extent that buying in £10 bags gives gram-equivalent prices of £50-£100 - heroin purities vary considerably, from around 15% up to 70% plus - such variations arise within the country of manufacture, as there is little evidence of the drugs being systematically cut in the UK market (average purities from police and customs seizures are similar).
Ecstasy prices continue to fall substantially, to the extent that individual tablets now sell most commonly for £5, and even small quantities can be obtained for around £2 each. This may be due to a combination of reduced demand (via health concerns about serotonin depletion) or more efficient distribution methods resulting in a saturated market. Although there were high ratings of the drug in 99-00 suggesting the image of the drug to be improving rather than deteriorating in the eyes of users as a whole, the significant drop in 2001 suggests the health message may finally be getting through.
LSD has fallen in popularity, with fewer police seizures, and fewer price reports, slightly higher than more recent years. The user-ratings of LSD have been falling steadily.

Notes for Editors
The Independent Drug Monitoring Unit - I.D.M.U. Ltd is a research consultancy specializing in the study of drug use and the drugs market in the UK. Our mission is to provide accurate, up to date and unbiased information to all parties in the drugs debate, and expert evidence to the Criminal Justiice System.
All data was collected from IDMU surveys using anonymous questionnaires distributed via pop-festivals, cannabis rallies, drug-subculture magazines, and by snowball samples. The 1984 data is derived from Quantitative Assessment of Illicit Substance Use, Atha MJ (1987), Birmingham University.
Respondents were asked to indicate the prices paid for a range of drugs at different market levels, as well as the proportion of different cannabis varieties they has used over the previous year, from which overall market shares were derived.
Subjective Ratings represent the average marks out of 10 ascribed to each drug by survey respondents as a whole (drug users, but not necessarily users of that particular drug)
Number reporting (drug) refers to the maximum number of respondents reporting prices for that drug in the smallest quantities - there may be respondents quoting prices for larger but not smaller quantities who would be unrecorded in these figures. Please note that in 2000 a higher proportion of respondents failed to complete the prices section of the questionnaire (which was on the last page), thus comparisons with the total respondents will be affected by the questionnaire layout, however comparisons of relative numbers reporting different drugs would be a valid exercise.
The 1995 survey was intended to fill the gap from results in 1994, which failed to ask prices for drugs other than cannabis, as this was a substantially smaller sample, more variation is to be expected. The 2001 survey was a relatively small sample compared to recent years, and geographically biased towards London & the South East, and the North West UK, thus the data may be less reliable than in previous years, however as London and the South East tend o have higher prices than the rest of the UK (with drugs, as with other commodities) the continuing fall in drugs prices may be greater over the rest of the UK. As several new questions were introduced in 2001 the same series will continue to be used for the 2002 survey.
Note on NCIS prices: The price lists published periodically by NCIS are supplied to the service by individual police forces (usually a single drugs liaison officer within each force). There is no standardised methodology for recording prices and the nature of price reports to police (i.e. from defendants, informants, test-purchases and/or general market intelligence), which vary considerably from the genuine cannabis ounces to the fictional £10 per gram (cannabis is very rarely sold in grams).
