From personal experience, I would suggest starting with one dropper. Once you have an idea on the effect, you could move to two droppers (my current dose).
You may feel the effect in terms of being more relaxed, but I would not say that I notice a specific 'high' feeling. Certainly not as you might get from smoking a joint or anything.
Cannabis is highly variable from person to person, and so its always advisable to start with a small dose of a new product, before slowly increasing the dose.
Hope this helps. I do recommend this product and manufacturer.
This tincture has a very high ratio of CBD to THC. As CBD counteracts the THC, which is the psychoactive component, it is unlikely you will feel any psychoactive feelings from this tincture of you stay within the recommended dosage. I have been a fan of this product for a long time and love the overall effect it has.
