A drug alert has been issued by the Berkshire Local Drug Information System (LDIS), advising users to exercise "extreme care." Harm reduction advice has been issued by the Berkshire LDIS for anyone in Newbury, Reading, and Wokingham who may be affected, or who uses crack cocaine. It is recommended that individuals carry naloxone, the opioid overdose reversal medication, which is available free from drug services and pharmacies. Test strips and confidential drug testing services are also recommended, with further information available from local drug services or the website wedinos.org. The alert states that the "safest choice is not to use," but that harm reduction advice and expert support saves lives.
