About this app

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.

Gives unprompted and unwanted notifications, imagine you're showing somebody your phone who doesn't know about your drug habits and a notification pops up. Decent application other than that and will revert to a good review when these are removed, or made opt-in only. EDIT: I know how to disable notifications system-wide but by that point it could already be too late. I maintain there should only be opt-in notifications, it's as simple as prompting the user when they first launch the application.

Hi Alexandre, I can understand your concerns. On Android, Push-notifications are enabled by default but you can easily turn them off by going to Settings - Apps & Notifications - KnowDrugs - Notifications. Alternatively you can also swipe a notification slightly to the right and disable by tapping on the settings-icon. Hope that helps!

Great, great app, my go to for drug research. Helped me find out a lot about things i've been planning. This helps me find exactly what i want 9/10 of the times i use it and i rarely have to turn to google. Only query is that when I'm scrolling through substance it can become really laggy and amd glitches all over the place causing it to take much more time to find a substance than it would otherwise. I'm using a sony xperia xz1 running android 9 if thats useful :)

Hi there, just wanted to let you know that the laggy scrolling on the Substance screen should be fixed with the last update. If you haven't yet, please update the app to the latest version, and let me know if the problem is solved. Thanks! Philipp

keeping up a good job. though shouldn't removed the long high bars for the categories, imo, quite handy if they worked. make the whole area active. Tripping people don't like two things: - scroll phone text for long - tap into huge buttons that don't work. rid of these two things and the crown is your, m8
