Yes, online Bakersfield marijuana doctors are legit.
They are real, certified doctors that work from a real clinic with a verified physical location. Like any practicing doctor, marijuana doctors also practice medicine professionally. The only difference is that they are tolerant towards the medical use of marijuana and are ready to write recommendations for those who need it.
Having said that, it is also true that you may face several scams and services claiming to provide medical marijuana recommendations online. In that case, you need to be careful and make sure that your doctor or clinic is legit.
