Plants around the house more toxic than marijuana

The other day, I was talking with a law enforcement friend about whether or not raw marijuana is harmful for kids. I told him that it’s not psychoactive in its raw form, so it might give a kid a tummy ache if he ate a bunch, but that’s about it.

He said, “I’ll bet there are a lot of common houseplants that are more toxic than marijuana.”

“There are,” I responded (trying to contain my enthusiasm).

“Can you send me a list? I’d love to have that the next time someone says something,” he said.

Always looking for an opportunity for a teaching moment, I hit my computer and searched for a list of poisonous houseplants as soon as I got home. I thought I’d share with you what I shared with him.

Rhubarb leaves

Many common houseplants that are toxic to children and pets include:

  • Asparagus Fern sap produces dermatitis; ingestion causes nausea, vomiting, cramping; berry ingestion very harmful to children.
  • English Ivy leaves can cause vomiting, breathing issues, convulsions, paralysis, coma; dermatitis is rare, but when it occurs, it can be severe (weeping blisters).
  • Peace Lily leaves can cause swelling of the lips, tongue and throat; the root sap can cause dermatitis

These plants are all more hazardous to children than cannabis, and yet we allow them to be grown in the home without restriction.

I wanted to make sure he understood clearly why raw cannabis is not psychoactive until it’s heated or otherwise decarboxylated, so I passed along this little gem:

Decarboxylating Cannabis: Turning THCA into THC

Tying it all together

To finish up, I sent him the link to Guide to Using Medical Cannabis from Americans for Safe Access. This is a nice explanation of cannabis basics including terpenes, cannabinoids, sativas, indicas, extracts and concentrates. Cannabis is a very complicated substance.

The response (makes it all worthwhile)

“This is great! Thanks!”
