Non-legal Cannabis in Germany is a surprisingly low margin product; profit is made through volume, which increases risk exposure. So it's not amazing for dealers, despite the large demand. It's abundance leads to a very competitive market (in Ballungsgebieten), like in other markets substitution though home production is always looming. For dealers in Berliner parks, there's also always competition with more reputable informal suppliers as well as medical trickle downs or substitutes. This leads to the incentive for dealers to steer consumption towards products with higher margin (or an increase of margin through lesser quality product).
