KnowDrugs is the easiest way to lookup drug testing results, pill warnings and drug alerts and provides you with drug info about more than 200 drugs, along with advice on harm reduction and safer use. Taking drugs always involves risks - however, if you do decide to take drugs, KnowDrugs can help you to take appropriate measures to reduce potential harms. DRUG INFORMATION & EDUCATION Check the profiles of more than 200 drugs for educational purposes: Stimulants like MDMA and Amphetamine, depressants such as Alcohol and Benzodiazepines or psychedelics like 2C-B, LSD and DMT. KnowDrugs provides you with drug education harm reduction advice, focusing on MDMA / Molly / Ecstasy and other psychoactive substances. Knowing about the wanted and unwanted effects of drugs, their duration, interactions and risks helps you to make more informed decisions, reduce risks and reflect upon your drug habits and consumption behaviour. DRUG CHECKING, PILL WARNINGS & DRUG ALERTS Search for drug name, substance or location, to find drug alerts from nearby and learn about their ingredients and dosage strength to avoid overdose and particularly dangerous cuts (e.g. PMA). Drug checking or pill testing is a way to reduce the harm from drug consumption by allowing users to find out the content and purity of substances that they intend to consume. This empowers users to make safer choices: to avoid more dangerous substances and combination and to use smaller quantities. If you don't have access to professional drug testing services, looking up recent drug testing results can still help you make a more informed decision about your consumption. HARM REDUCTION & RESPONSIBLE DRUG USE Harm reduction aims to minimize the harms associated with recreational substance use. The harm reduction approach follows from the idea that substance use is a high-risk activity that innately entails the possibility of injury, addiction, and death. Therefore, the best strategy one can employ (outside of avoiding use entirely) is to take appropriate measures to mitigate its potential harms. KnowDrugs highlights the harm-potential of more than 200 substances and demonstrates strategies on how to reduce the harms associated with the consumption of drugs. KNOWDRUGS CAN ALSO HELP YOU TO: - learn how to spot and react in case of an emergency, take care of someone experiencing a bad trip at a party or festival - find a free and confidential counselling service which accepts you and your personal choices, and helps you develop the right strategies and competencies if you want to change something about your consumption behaviour. Note: Always check in with your doctor in addition to using the app and before making any medical decisions. This app is not a replacement for professional medical and/or psychological help.
