A new harm reduction campaign by drug safety organisation The Loop in partnership with the Metro newspaper is warning clubbers to stay safe as venues open after 18 months of lockdown restrictions. Clubbers are being urged to pace themselves and not \u2018make up for lost time\u2019 \u2018High Alert\u2019 is urging people to pace themselves and not \u2018make up for lost time\u2019 by taking more drugs than they otherwise would have, especially as their tolerance may be reduced. The campaign is urging people to \u2018Go slow, stay low\u2019, and avoid taking entire ecstasy pills. According to EMCDDA\u2019s recent European drug report the MDMA content of ecstasy tablets remains high, along with purity levels of MDMA powder, with The Loop issuing warnings about pills containing three or four times the common adult dose of MDMA. \u2018High-strength drugs are one of the main factors behind an increase in drug overdoses and deaths for \u201cparty drugs\u201d,\u2019 the campaign states, adding that there is \u2018good reason\u2019 to think that there will still be a number of these drugs in circulation over the summer. \u2018At a time of high-strength drugs it is particularly important to start with smaller amounts,\u2019 it says. \u2018Remember, you can always take more of a drug, but you can never take less.\u2019 It also warns festival-goers and clubbers to be wary of substances such as cathinones being mis-sold as party drugs, and urges people to use drug-checking services where available. A recent study by the University of Liverpool found that using these can permanently influence behaviour, with many people saying they\u2019d become more cautious about buying drugs from strangers or using multiple substances and around a fifth of respondents saying they\u2019d continued to take smaller doses since the intervention.
