Flush Weed Roaches Down The Toilet

As weed becomes legal in the United States, weed sales and consumption are steadily increasing. This has led companies and us stoners in general to figure out how to handle the waste from the marijuana we consume.

There is no doubt that there is a lack of information on how to dispose of marijuana waste and this is because it is relatively new, so you may already think that the best option is to flush weed roaches down the toilet.

But is this really a good idea?

Whether you’re currently working with cannabis growers or you’re just another stoner in the community, here’s everything you need to know about getting rid of marijuana the right way!

What is Considered Cannabis Waste?

In order to know how to dispose of cannabis correctly, we must first be absolutely clear about what is actually considered cannabis waste.

Basically cannabis waste with any direct product or by-product of cannabis production and depending on whether it contains chemical compounds or not, it should be disposed of in a totally different way.

In some states of the country, it is the case that almost any element that comes into contact with cannabis is considered waste. Below we will mention some elements and what they may or may not include:

  • Excess cannabis material: Clippings, plant roots, and any unused marijuana.
  • Expired weed products: Includes CBD products, infusions, and cannabis oils.
  • Unused cannabis gadgets: Vapes, capsules, or packaging used for cannabis storage.
  • Growing materials: Soil, sponges, and any element used for cultivation.

How to Dispose of Marijuana?

Laws and regulations in the country are getting stronger and stronger on this issue and rightly so. Their biggest concern is that improper disposal could result in secondary cultivation and the black market.

The idea is to prevent thieves from retrieving some cannabis material from dumpsters to sell to unsuspecting buyers or use it themselves and end up with serious health problems.

The proper way to dispose of marijuana waste is to render it completely unrecognizable and unusable. There are at least two (fairly well-known) different ways to do this: permitted landfill or weed incineration.

Permitted landfill

There are thousands and thousands of landfills across the country, but not all of them are suitable for disposing of weed and its components.

Landfills suitable for accepting marijuana waste are usually well marked so that both businesses and stoners can easily identify them and also have systems in place to prevent theft or misuse!

Cannabis incineration

Without a doubt, this is the easiest, safest, and most cost-effective way to dispose of cannabis waste. But don’t be fooled, it’s not like you can put some gasoline in your backyard and set it on fire.

Burning dispose of marijuana can potentially create an effect similar to when you smoke a joint, so it is necessary to do it in special machines that are responsible for isolating and burning any remaining THC or CBD.

Ideally, you should turn to companies like Rader Environmental, which specialize in the handling and incineration of all types of marijuana waste.

Can’t You Just Flush Weed Fown the Toilet?

It’s a question that comes up quite often, in most cases it’s parents who have found their child’s stash of herbs and want to get rid of it.

However, it is our duty to report that this is not a good idea! In fact, there are two major problems with this premise:

  1. Flushing weed down your toilet may be harmful to the environment and may cause damage to the pipes in your home.

  2. You can end up clogging the pipes and end up with a house full of water and the cannabis you tried to throw away. (This has already happened to some dealers in the UK).

Can weed clog a toilet?

This is something that in most cases does not happen. However, if you intend to do it with a large amount of weed the chances of it happening are quite high.

When should you throw away a joint?

You should throw it away when it is moldy or broken, otherwise, it can still be smoked. The only disadvantage is that it will probably end up burning much faster and its potency will not be the best.

Are there notification requirements for the disposal of cannabis?

In fact, there are specific reporting requirements for disposal (at least for California), as well as other general requirements. These can be found in section 15049 of the Medical and Adult-Use Cannabis Regulations.

Can you throw edibles away?

Edibles can be disposed of with general non-hazardous plant waste and therefore do not need to be treated in an authorized waste facility.


Whether you’re a grower, a business, or a conventional stoner, you should make sure you’re well-versed in local, federal, and state laws on how to properly dispose of cannabis waste.

Avoid being one of the many who end up flushing their weed roaches down the toilet, contributing to the overall pollution of our environment!

Make sure you are a responsible consumer and if in doubt, contact the appropriate authorities immediately so they can assist you and guide you through the marijuana disposal process.
