No, they don't. You are permitted to grow 1/10th of an acre for personal consumption, no tax involved.
They expect the tax if you make your own fuel as well.
I know nothing about that.
That is not the way I understand it Gabz but the wider point is that divide and conquer taxation is a slippery slope.
I would NEVER yoke my fellow man with disproportionate taxation.
4000 sq ft of tobacco is plenty for this household.
