The mysteries of the brain's own cannabinoid system exposed and explained.

Though cannabis has been used, for pain or pleasure, for over 4000 years, only lately have we learned, first, what makes it work and, more recently, how. Unraveling the mystery of the human brain's special relationship with a psychoactive chemical derived from a plant--tetrahydrocannabinol, or THC, specifically--neuroscientist Linda Parker recounts the discovery of the brain's own THC, called endocannabinoids, and describes the remarkable brain chemical system this discovery revealed.

In expert yet accessible terms, Cannabinoids explains what we know about this system, how it functions, and how it interacts with the plant materials in cannabis. Parker explores the role of the endocannabinoid system in regulating emotion, anxiety, depression, psychosis, learning, memory, feeding, nausea, pain, epilepsy, and neurological disorders--as well as, naturally, the brain's reward system. Examining the link between anecdotal reports and the current scientific literature, the book offers a balanced presentation of the scientific evidence for the medicinal use of marijuana, providing a timely intervention in ongoing debates about cannabis's medicinal value and its legal status.

I FINALLY GOT AN INDESTRUCTIBLE TOY!!! Yes!
Color: Green, Size: Large(50-90 lbs), Color: Green, Size: Large(50-90 lbs)
This one is TRULY indestructible! I’ve been purchasing one after another trying to find something that she cannot break in 5 mins. Everything I’ve ordered (until this one) has been SHREDDED in 3-10 minutes! It’s TRUE RUBBER! I’m so happy with my purchase! See the picture below- we’ve had it for a couple months now and she has barely chewed off just a few small nubs! Which she’s proud of 😆 If you truly want a challenge for your CRAZY DOG- you will love this squeaker!

Rough and tough chew toy
Color: Azure, Size: Large(50-90 lbs)
This is a thick and heavy duty toy to stand up to medium to large dogs who are heavy chewers. And the rough textures really encourages my dog and it is the perfect size to throw and play fetch. Very sturdy…I bought around Christmas and it’s almost may and she hasn’t destroyed it yet!!!

Very sturdy and strong toy
Color: Green, Size: Large(50-90 lbs)
This keeps my dog busy. He has a blast with it. It is a little bit big for his mouth, but he still seems to have fun with it. My dog is German Shepherd and Australian Shepherd.

Awesome squeaker toy!
Color: Green, Size: Large(50-90 lbs)
Noise level is expected. It’s a squeak toy. If you get annoyed by your dog having fun, get outta here. It’s a bigger toy so I don’t worry about choking. It’s bouncy and a tough material for our tough chewer. Color is whatever! Great toy.

It was fun while it lasted.
Color: Green, Size: Large(50-90 lbs)
This is a tough chew toy, but yep, it still got destroyed after a few uses. So my Siberian Husky strategically destroys the squeak in everything immediately. This one actually took some time. It's not super squeaky and is more challenging to make it squeak. I was pleasantly surprised that it the squeaker lasted a couple weeks. For the record my Pitbull got to it the 3rd week and it was completely destroyed in 2 further days. This is a very hard chew toy and I wouldn't recommend this unless your dog is also a destroyer of a the tougher toys. Even though it was still demolished they had a great time with it and it still lasted longer than most. I hope that helps and I hope you have a happy day.
