About us

Who we are and what we do!

Founder / CEO

Sven Friedrich

Hello! My name is Sven Friedrich and I am the founder of the information portal quitweed.de and the withdrawal program. In addition, I am a lecturer at the German Cannabis Academy, where I am responsible for prevention work.

I founded this project in 2014 to provide affected individuals with sufficient information about cannabis withdrawal. That was the beginning of our success story!

Nowadays, over 20 people are involved in this project, including psychologists, addiction counselors, health and motivation coaches, and experts in the body’s endocannabinoid system.

My goal is to educate cannabis users about the risks and help them with withdrawal. Our 3 phases of cannabis withdrawal are the basis for this.

Quit smoking weed

I had tried to quit smoking weed 4 times in the last 2 years. Unfortunately, I never managed to stay clean for more than 1–2 weeks. After I acquired your knowledge, I was optimally prepared for the next and final attempt. It's been almost 9 months since I've been clean now and I feel better than ever!

I was completely clueless when I wanted to start the cannabis withdrawal. Additionally, I had heard so many horror stories about withdrawal symptoms. Luckily, I came across the withdrawal program. With all the tips and over-the-counter remedies, the withdrawal symptoms were almost not noticeable!

After 25 years, it was finally time for me to start a new chapter in my life. With the help of the withdrawal program, the cannabis withdrawal went smoothly. It wasn't even that hard for me. What scared me was the future. Fortunately, there is your motivation coach! Thanks to him, I now know exactly what I want to do with my life.

Your community was exactly what I needed. I always lacked the support to stick to the detox until the end. Nobody could understand what I was going through and then it was always too much for me. With the motivation of the community, it went much, much better! As they say: A problem shared is a problem halved. Thank you!
