I am note sure what an ideal dose of CBD is, and I doubt anyone does. But it would be nice to have a vague idea to start.
This is where a qualified MMJ doctor comes in handy, under medical MJ, a doctor monitors and helps, especially for people that are not familiar with MJ....they also RX you the dosage, the lowest to mid usually for beginners and work from there. It's like individualized for each person actually (dosage and strains) plus different doses and strains help with a variety of issues too. It also varies as to how long it takes to work and such for each person and some cannot tolerate it at all (but that doesn't mean it should be knocked because like everything else, what works for some doesn't work for all.
