Our Vision

As an inspiration for weR we see that the full potential and benefits of cannabis as a useful consumer good can be integrated into our societies and can be continually developed as an approach to medical therapies. weR is designed as an automatic cannabis rolling device to meet the needs of recreational users as well as to ensure accessibility for chronically ill or physically challenged users for medical purpose.

See my beauty. Witness my elegance. Unleash my power.

Our Mission

With our ability for technological innovation and advanced engineering we aim to facilitate cannabis use and enable consumers worldwide to use an automated cannabis rolling device and joint dispenser, whether for recreational or medical use.
