Water conservation isn’t just a personal issue; businesses need to keep an eye on their water usage, too. Even some businesses that aren’t entirely on the up-and-up. I’m assuming the people reading this post have already read this story or a similar one, about how the state is cracking down on illegal marijuana farms because of their heavy water usage.And that got me to thinking: this blog has covered virtual water usage for common food items, clothing, and cleaning products. So what about virtual water usage in drugs, both legal and illegal? Please note that The Longest Straw isn’t endorsing or condemning drug use, but we are aware that many people partake, and that could include some of our readers, so let’s take a look at the virtual water impact of several common drugs. Let’s begin with a legal drug: cigarettes. A bit of googling will reveal that tobacco has one of the highest water-footprints on earth. Typical agriculture requires 7800 cubic meters of water in a traditional growing cycle.  And that’s not even counting all the various other ingredients that your many tobacco companies like to throw into their cigarette recipes. We’ve already touched base on alcohol’s water footprint  in a previous post, so let’s move on to the article that inspired this post: marijuana. A single marijuana plant uses a total of between 5 and 10 gallons of water  in its life, and your average plant will produce between 1.5 – 2 ounces. A regular vegetable, like broccoli, will use about half as much water. Imagine the impact of a giant field of the crop – no wonder the state is cracking down on water usage. As we’ve mentioned before, sometimes, saving water means doing without some luxuries. If you’ve ever needed an excuse to quit smoking, cut back on your drinking, or just say no to that joint, look at it this way - you could have a virtual water impact of 0 if you just cut back on a few of the vices mentioned in this article.
