Well, to be clear, I myself have not tried marijuana -- really, never have. I've smelled others using it, but I've never had a desire to try it myself; hey, a beer or two does me in, so I've always been nervous about trying anything stronger. But I do have friends who extol its virtues: it eases stress and relaxes you; it has health properties, etc., etc.
This morning, I really needed a stress-easer! I thought my head was going to explode with that rush of panic that hits when you realize you didn't do something you were supposed to do. Thankfully, I quickly discovered that I had more time than I realized, but my head was still feeling the effects of the panic, on top of having had a half cup of coffee on an empty stomach! So, I sat down, took a deep breath, and started to knit a row on the sweater I'm making (more on that later...). By the end of the row, I felt soooo much better.
That's what got me thinking about why knitting and crocheting really are superior forms of relaxation than the usual chemical ways people seek to ease their stress. Specifically,
1) It's Cheaper.
I'm told that 1 gram of the good stuff costs about $20. Hey, for that price, you can buy 100 grams (which is about 350-400 yards, depending on the thickness of the yarn) of hand-dyed wool yarn or 300-400 grams of a fine quality manufactured yarn. And it'll take a lot longer to use up the yarn than smoke one joint!
2) You Know What You're Getting
One of my big fears about trying marijuana is a lack of knowledge about exactly what's in it or if it's been "laced" with anything (maybe now with legalization and regulation that's less of a concern), but have you ever heard of a yarn ingredient scandal??
3) And, If You Don't Like It, You Can Return It
I doubt your pot source is going to be willing to take back any unused portion of your purchase, but local yarn shops usually have reasonable return policies.
4) You Can Do It Legally in Public
In fact, Worldwide Knit In Public Day is coming up on June 18, 2016, and the Upper Northwest Knitters of DC are celebrating at Laliguras Restaurant on Connecticut Avenue, details here! Though I guess you could say that both activities seem to still have some stigma attached to them :-).
5) No Munchies
It's hard to eat and stitch (messy in the least), so it's actually a great way to inhibit mindless munching, which actually further reduces your costs and is better for your health ;-)
Now, arguably, the creative aspects of both could make the two activities compatible; it would be interesting to hear about experiences in which people have tried to crochet while smoking pot!
