Toronto | Corona beer maker Constellation Brands will infuse another $US4 billion ($5.5 billion) into Canada's top cannabis producer Canopy Growth, the biggest investment in the industry, to capitalize on booming demand for marijuana.

Constellation, among the first big alcohol makers to invest in the marijuana industry, pumped almost $US200 million in Canopy last year in a deal to produce a non-alcoholic cannabis-based beverage.
