High THC Strains
Strains high in THC will often have more potent effects. So whatever effect that particular strain has, if it has high levels of THC those effects will usually be more pronounced. While THC has some medicinal effects and works in conjunction with CBD, strains high in THC will typically be more mentally stimulating and have euphoric effects. Too much THC is often associated with having negative experiences on cannabis. So more THC does not mean its a better strain or better quality cannabis.
