NO NO NO. This is a bubble in so many ways. And ironically I think a lot of the suckers investing are people who haven't actually smoked enough pot to understand the product.
Cannabis is very easy to grow -- MUCH easier to grow and cure than tobacco. But with tobacco, a cigar afficionado might consume upwards of half an ounce of tobacco in an evening, or at least in a weekend. With cannabis, even a fairly enthusiastic user might use a half ounce of flower buds in a YEAR. Modern marijuana is a very powerful drug; a tiny amount goes a long way.
When Oregon legalized, they want from severe shortages to ridiculous oversupply and price crashes in like 9 months. California by itself is probably growing more cannabis right now than the entire country is able to consume. It's just piling up in warehouses. Prices are crashing. Growers in Northern California who have been at it for 40 years are quitting the business because they can't make a living any more.
And it's just the start -- new large scale growing operations are starting in Canada and all over the country.
This industry is going to grow and grow and then the bubble will pop and 90% of investors, maybe 99%, will lose everything.
It's like the Yukon gold rush -- in the end the only real durable business might be the people who service and supply the industry -- the people who made pickaxes and tin pans and backpacks for the prospectors.
The folks who make grow lights and build warehouses and cannabis refining equipment and vape pens -- they'll make money. But even they will probably experience a roller coaster ride.
