Yes, in theory you can drive while you have taken a microdosing. It is not prohibited because the dosage falls within what is legally permitted.
Still, it is important to act responsibly yourself. Do rather not drive if you take a microdosing for the first time. Also don’t drive if you took a little too much for your feeling or if you don’t feel comfortable with your intaking.
Conversely, a microdosing will improve your focus and sight, so it can’t harm to driving. In practice you may even be sharper and so respond better to the situation around you.
Our advice is to always experiment in a safe environment to find out which microdosization suits you best. If it feels too strong, you have taken too much. It is then not wise to go driving or to participate in traffic in a different way.
