Oh yeah!

There are two types of marijuana:

Sativa and Indica. Neither is "better", it's just personal preference. Most marijuanas are a mixture of the two strains.

Generally, Cannabis Sativa gives you more of a "heady high". It's great for going out with friends to a movie or something. It's great for if you're going to a concert or when you're playing a musical instrument. Typical Sativa leaves are long and skinny. My personal favorite. The "best" Cannabis Sativa strains are
Durban Poison
Haze Marijuana
Mauwie Wauwie
Purple Haze Marijuana

Secondly, there is Cannabis Indica. Indica bud is usually the exact opposite of Cannabis Sativa... users report a strong body buzz sensation that is generally very pleasurable. Dancing and moving around, as well as sexual sensations and sleeping are generally very enjoyable activities when under the influence of Cannabis Indica. Indica Leaves are characterized by short, fat leaves. Popular strains of Cannabis Indica are:
White Widow Marijuana
Northern Lights Marijuana
Hawaiian Marijuana
Skunk Marijuana

Generally, eating and smoking marijuana give two different types of highs. When marijuana is smoked, generally people will be feeling the sensations in their head, bronchial tubes, and lungs. Breathing feels incredible. The broncial tubes are opened, allowing tar, mucus, and dust to be coughed out. When eaten, the THC goes into the bloodsteam and is carried all over the body, increasing tactile sensations. After smoking marijuana material, the onset usually occurs a minute or two after combustion. After ingestion, the onset can occur as much as an hour afterwords, depending on how much food is in the stomach and personal metabolic rates.
