Whisk together garlic, ginger, stock, vinegar, oyster sauce, sesame oil, sugar, salt, pepper, and cornstarch until well combined. Whisk in melted cannabis infused butter until well combined and mixture is emulsified. You can alternately prepare sauce in a small food processor. Set aside.
Heat a wok over high heat. Add 2 teaspoons oil and swirl to coat wok. Add shrimp and stir fry just until cooked, about 4 to 5 minutes. Remove shrimp from wok and set aside.
Add remaining 2 teaspoons oil to wok and swirl to coat. Add asparagus, mushrooms, and green onions to wok and stir fry until crisp-tender, about 6 minutes.
Return shrimp to wok and stir to combine ingredients. Stir sauce and pour over ingredients in wok. Cook, stirring constantly, for about a minute or until sauce heats through, thickens, and evenly coats the food. Serve immediately over rice or noodles.
** Oyster Sauce, a staple of Chinese cuisine, is a thick, dark brown sauce made from ground dried oysters. Available at Asian food markets or well stocked grocery stores, oyster sauce will keep indefinitely in your refrigerator.
