People from Trinidad – first – do not mix grass and tobacco but after the joint – usually – they smoke a cigarette.
So in Trinidad, people do smoke a Roll On i.e. a Joint Rolled On the cigarette.
And the Roll On when you smoke the grass is called Funk.
Recommended for Tobacco Smokers
If you do, try the roll on and you do not feel the high: remove the filter or at least half of the filter from the cigarette
The video does not mention this particular but the filters – especially those of light cigarettes – stop almost all THC. A small filter such as the Zwister is, instead, suitable for joints.
