I would at least call a qualified reptile vet and ask about marijuana exposure. Actually, I'd recommend she get her iguana to a vet anyway. Iguanas have many organisms in their digestive tract. If kept in balance things are fine. But if stressed, sometimes the balance can go wacky. The bad gut flora will overwhelm the good. So I would take the iguana in for a fecal at the very least. The iguana has been under a lot of stress. Moving to friends and back home. Who knows how well they cared for it. Then the marijuana. It may not harmed her directly but it would have stressed her more at the very least.
Pellets isn't a very good choice. And if dry can contribute to dehydration. Iguanas in captivity are constantly suffering from dehydration to one degree or another. Pellets will pull the water from the iguanas body. Chronic dehydration can lead to kidney damage and kidney failure. Also some pellets contain animal protein or their byproducts which also damages the kidneys. Most iguanas due to these issues die at the age of 5-7 instead of living to 15-20 years. I recommend she changes the iguanas diet
DIET :
An iguana's diet should contain the following each day:
70-80% calcium rich greens: Collards, mustard greens, turnip greens, dandelions, arugula, watercress are the better ones. Kale, beet greens, chicory greens and escarole used in combination with the better greens are also good. Stay away from lettuces (except for a very occasional treat) because they have very very little nutrition if at all and the iguana will fill up on it and not eat the nutritional food--in other words it is junk food. Spinach should only be used occasionally because it is way too high in oxalates and phosphorous. The oxalates bind with the calcium making it indigestible and the phosphorous binds with calcium in the blood making the calcium there useless. But spinach is high in iron so it is good if only used very occasionally (1-2x a month maybe).
20-30% vegetables: Winter squash (acorn, butternut, kabocha, ect..), green beans, snap peas, okra, parsnip, yucca root. Summer squash (zucchini, yellow, Mexican or white, ect...) occasionally is good too. Red, yellow, and orange bell peppers are good color enhancers.
No more than 10% fruit: Blueberries, figs, mango, papaya, and prickly pear (cactus) are the better fruits. Strawberries, raspberries, black berries and melons are good. Flowers should be considered a fruit
percentages based on volume
ABSOLUTELY NO ANIMAL PROTEIN OR BY PRODUCTS
What are the iguanas temps?--Basking?--Ambient (overall)?--Cool area?--Nighttime?
What UVB bulb does she use?--Type?--Brand?
What is the distance from the UVB bulb and the skin of the iguana?
